Chromosomal DNA is continuously subjected to exogenous and endogenous damaging insults. In the presence of DNA damage cells activate a multi-faceted checkpoint response that delays cell cycle progression and promotes DNA repair. Failures in this response lead to genomic instability, the main feature of cancer cells. Several cancer-prone human syndromes including the Ataxia teleangiectasia (A-T), the A-T Like Disorder (ATLD) and the Seckel Syndrome reflect defects in the specific genes of the DNA damage response such as ATM, MRE11 and ATR. DNA damage response pathways are poorly understood at biochemical level in vertebrate organisms. We have established a cell-free system based on Xenopus laevis egg extract to study molecular events underlying DNA damage response. This is the first in vitro system that recapitulates different aspects of the DNA damage response in vertebrates. Using this system we propose to study the biochemistry of the ATM, ATR and the Mre11 complex dependent DNA damage response. In particular we will: 1) Dissect the signal transduction pathway that senses DNA damage and promotes cell cycle arrest and DNA damage repair; 2) Analyze at molecular level the role of ATM, ATR, Mre11 in chromosomal DNA replication and mitosis during normal and stressful conditions; 3) Identify substrates of the ATM and ATR dependent DNA damage response using an innovative screening procedure.

Increasing crop yield to feed the world is a grand challenge of the 21st century but it is hampered by diseases caused by filamentous plant pathogens. The arms race between pathogen and plant demands constant adjustment of crop germplasm to tackle emerging pathogen races with new virulence features. To date, most crop disease resistance has relied on specific resistance genes that are effective only against a subset of races. We cannot solely rely on classical resistance genes to keep ahead of the pathogens. There is an urgent need to develop approaches based on knowledge of the pathogen’s Achilles heel: core plant processes that are required for pathogen colonization. Our hypothesis is that disease resistance based on manipulation of host accessibility processes has a higher probability for durability, and is best identified using a broad host-range pathogen. I will employ the filamentous pathogen Phytophthora palmivora to mine plant alleles and unravel host processes providing microbial access in roots and leaves of monocot and dicot plants. In Aim 1 I will utilize plant symbiosis mutants and allelic variation to elucidate general mechanisms of colonization by filamentous microbes. Importantly, allelic variation will be studied in economically relevant barley and wheat to allow immediate translation into breeding programs. In Aim 2 I will perform a comparative study of microbial colonization in monocot and dicot roots and leaves. Transcriptional profiling of pathogen and plant will highlight common and contrasting principles and illustrate the impact of differential plant anatomies. We will challenge our findings by testing beneficial fungi to assess commonalities and differences between mutualist and pathogen colonization. We will use genetics, cell biology and genomics to find suitable resistance alleles highly relevant to crop production and global food security. At the completion of the project, I expect to have a set of genes for resistance breeding.

A significant advance in the field of development has been the appreciation that radial glial cells are progenitors and give birth to neurons in the brain. In order to advance this exciting area of biology, we need approaches that combine structural and functional studies of these cells. This is reflected by the emerging realisation that dynamic interactions involving radial glia may be critical for the regulation of their proliferative behaviour. It has been observed that radial glia experience transient elevations in intracellular Ca2+ but the nature of these signals, and the information that they convey, is not known. The inability to observe these cells in vivo and over the course of their development has also meant that basic questions remain unexplored. For instance, how does the behaviour of a radial glial cell at one point in development, influence the final identity of its progeny? I propose to build a research team that will capitalise upon methods we have developed for observing individual radial glia and their progeny in an intact vertebrate nervous system. The visual system of Xenopus Laevis tadpoles offers non-invasive optical access to the brain, making time-lapse imaging of single cells feasible over minutes and weeks. The system s anatomy lends itself to techniques that measure the activity of the cells in a functional sensory network. We will use this to examine signalling mechanisms in radial glia and how a radial glial cell s experience influences its proliferative behaviour and the types of neuron it generates. We will also examine the interactions that continue between a radial glial cell and its daughter neurons. Finally, we will explore the relationships that exist within neuronal progeny derived from a single radial glial cell.

What processes shape vertebrate diversity through deep time? Approaches to this question can focus on many different factors, from life history and ecology to large-scale environmental change and extinction. To date, the majority of studies on the evolution of vertebrate diversity have focused on relatively simple metrics, specifically taxon counts or univariate measures, such as body size. However, multivariate morphological data provides a more complete picture of evolutionary and palaeoecological change. Morphological data can also bridge deep-time palaeobiological analyses with studies of the genetic and developmental factors that shape variation and must also influence large-scale patterns of evolutionary change. Thus, accurately reconstructing the patterns and processes underlying evolution requires an approach that can fully represent an organism’s phenome, the sum total of their observable traits. Recent advances in imaging and data analysis allow large-scale study of phenomic evolution. In this project, I propose to quantitatively analyse the deep-time evolutionary diversity of tetrapods (amphibians, reptiles, birds, and mammals). Specifically, I will apply and extend new imaging, morphometric, and analytical tools to construct a multivariate phenomic dataset for living and extinct tetrapods from 3-D scans. I will use these data to rigorously compare extinction selectivity, timing, pace, and shape of adaptive radiations, and ecomorphological response to large-scale climatic shifts across all tetrapod clades. To do so, I will quantify morphological diversity (disparity) and rates of evolution spanning over 300 million years of tetrapod history. I will further analyse the evolution of phenotypic integration by quantifying not just the traits themselves, but changes in the relationships among traits, which reflect the genetic, developmental, and functional interactions that shape variation, the raw material for natural selection.

Over the past decade, the media, international organisations, as well as policy-making bodies have voiced increasing concern about a growing overlap between the criminal and political spheres in South Asia. Many 'criminal politicians' are accused not simply of embezzlement, but of burglary, kidnapping and murder, so that the observed political landscape emerges not only as a 'corrupt', but also a highly violent sphere. This project is a collaborative and cross-national ethnographic study of the criminalisation of politics in India, Pakistan and Bangladesh. Bringing together local-level investigation, surveys and historical analysis, the project will produce comprehensive political ethnographies in sixteen sites across the subcontinent, providing empirical material and theoretical directives for further charting of the virtually unexplored terrain of extra-legal muscular politics in the region. Central to the proposed programme of research are the following interrelated objectives: 1) To further develop the method of collaborative political ethnography by designing, collecting and producing case studies which will allow us to write thematically across sites; 2) To generate policy relevant research in the fields of security, conflict, democracy and development; 3) To produce capability by forging an international network of scholars on issues related to democratisation, violence, crime and support the work and careers of the project's 4 Post-docs. The study capitalises on previous research and skills of the PI in the cross-cultural study of democracy and muscular politics in the global South. All members of the research team have expertise in ethnographic research in the difficult spheres of criminal politics, informal economies, and political violence and are hence well and sometimes uniquely equipped to pursue this challenging research thematic.

Within a 12 month period, 20% of adults will meet criteria for one or more clinical anxiety disorders (ADs). These disorders are hugely disruptive, placing an emotional burden on individuals and their families. While both cognitive behavioural therapy and pharmacological treatment are widely viewed as effective strategies for managing ADs, systematic review of the literature reveals that only 30–45% of patients demonstrate a marked response to treatment (anxiety levels being reduced into the nonaffected range). In addition, a significant proportion of initial responders relapse after treatment is discontinued. There is hence a real and marked need to improve upon current approaches to AD treatment. One possible avenue for improving response rates is through optimizing initial treatment selection. Specifically, it is possible that certain individuals might respond better to cognitive interventions while others might respond better to pharmacological treatment. Recently it has been suggested that there may be two or more distinct biological pathways disrupted in anxiety. If this is the case, then specification of these pathways may be an important step in predicting which individuals are likely to respond to which treatment. Few studies have focused upon this issue and, in particular, upon identifying neural markers that might predict response to cognitive (as opposed to pharmacological) intervention. The proposed research aims to address this. Specifically, it tests the hypothesis that there are at least two mechanisms disrupted in ADs, one entailing amygdala hyper-responsivity to cues that signal threat, the other impoverished recruitment of frontal regions that support cognitive and emotional regulation. Two series of functional magnetic resonance imaging experiments will be conducted. These will investigate differences in amygdala and frontal function during (a) attentional processing and (b) fear conditioning. Initial clinical experiments will investigate whether Generalised Anxiety Disorder and Specific Phobia involve differing degrees of disruption to frontal versus amygdala function during these tasks. This work will feed into training studies, the goal being to characterize AD patient subgroups that benefit from cognitive training.

Many aphid species are restricted to one or few host plants, while some aphids, many of which are of agricultural importance, can infest a wide range of plant species. An important observation is that aphids spend a considerable time on nonhost species, where they probe the leaf tissue and secrete saliva, but for unknown reasons are unable to ingest phloem sap. This suggest that aphids, like plant pathogens, interact with nonhost plants at the molecular level, but potentially are not successful in suppressing plant defenses and/or releasing nutrients. To date, however, the plant cellular changes and the involvement of immune response, such as ETI and PTI, in aphid-host and -nonhost interactions remain elusive. The aim of the proposed project is to gain insight into the level of cellular host reprogramming that takes place during aphid-host interactions, the cellular processes involved in aphid nonhost resistance, and the role of aphid effectors in determining host range. We will compare interactions of two economically important aphid species, Myzus persicae (green peach aphid) and Rhopalosiphum padi (bird cherry oat aphid), with host and nonhost plants. We will investigate local changes in plant cellular processes during aphid-host and -nonhost interactions using microscopy and biochemistry approaches. We will apply a comparative transcriptomics approach and functional assays to identify aphid effectors as potential determinants of host range. Herein we will specifically looks for aphids-species specific effectors and those that are expressed in specific host interactions. To gain insight into molecular mechanisms of effector activities we will identify host targets and investigate the contribution of effector-target interactions to host range. The expected outcomes of the project will, in the long term, contribute to the development of novel strategies to control infestations by aphids and potentially other pests and pathogens, thereby improving food security.

Most historians work in archives, but generally have not made archives into their primary object of research. While we tend to be preoccupied by documentary loss, what is striking is the sheer amount of paperwork preserved over the centuries. We need to study the reasons for this preservation. This project wishes to study the history of the archives and of the chanceries that oversaw their production storage and organization in late medieval and early modern Italy: essentially from the creation of the first chanceries in city-states in the late twelfth century to the opening of the Archivi di Stato that, after the ancient states’ dissolution, preserved documents as tools for scholarship rather than administration. Because of its fragmented political history, concentrating on Italy means having access to the archives of a wide variety of regimes; in turn, as institutions pursuing similar functions, archives lend themselves to comparison and therefore such research may help us overcome the traditional disconnectedness in the study of Italy’s past. The project proposes to break significantly new ground, first, by adopting a comparative approach through the in-depth analysis of seven case studies and, second, by contextualising the study of archives away from institutional history in a wider social and cultural context, by focusing on six themes researched in six successive phases: 1) the political role of archives, and the efforts devoted by governments to their development; 2) their organization, subdivisions, referencing systems; 3) the material culture of documents and physical repositories as well as spatial locations; 4) the social characteristiscs of the staff; 5) the archives’ place in society, including their access and misuse; 6) their use by historians. As implied in the choice of these themes, the project is deliberately interdisciplinary, and aims at the mutually beneficial exchange between archivists, social, political cultural and art historians.

The nature of consciousness is one of the great unsolved mysteries of science. Although the global research effort dedicated to explaining how consciousness arises from neural and cognitive activity is now more than two decades old, as yet there is no widely accepted theory of consciousness. One reason for why no adequate theory of consciousness has yet been found is that there is a lack of clarity about what exactly a theory of consciousness needs to explain. What is needed is thus a model of the general features of consciousness — a model of the ‘architecture’ of consciousness — that will systematize the structural differences between conscious states, processes and creatures on the one hand and unconscious states, processes and creatures on the other. The aim of this project is to remove one of the central impediments to the progress of the science of consciousness by constructing such a model. A great many of the data required for this task already exist, but these data concern different aspects of consciousness and are distributed across many disciplines. As a result, there have been few attempts to develop a truly comprehensive model of the architecture of consciousness. This project will overcome the limitations of previous work by drawing on research in philosophy, psychology, psychiatry, and cognitive neuroscience to develop a model of the architecture of consciousness that is structured around five of its core features: its subjectivity, its temporality, its unity, its selectivity, and its dimensionality (that is, the relationship between the levels of consciousness and the contents of consciousness). By providing a comprehensive characterization of what a theory of consciousness needs to explain, this project will provide a crucial piece of the puzzle of consciousness, enabling future generations of researchers to bridge the gap between raw data on the one hand and a full-blown theory of consciousness on the other

Since 2012, over 4 million people have fled Syria in ‘the most dramatic humanitarian crisis that we have ever faced’ (UNHCR). By November 2015 there were 1,078,338 refugees from Syria in Lebanon, 630,776 in Jordan and 2,181,293 in Turkey. Humanitarian agencies and donor states from both the global North and the global South have funded and implemented aid programmes, and yet commentators have argued that civil society groups from the global South are the most significant actors supporting refugees in Lebanon, Jordan and Turkey. Whilst they are highly significant responses, however, major gaps in knowledge remain regarding the motivations, nature and implications of Southern-led responses to conflict-induced displacement. This project draws on multi-sited ethnographic and participatory research with refugees from Syria and their aid providers in Lebanon, Jordan and Turkey to critically examine why, how and with what effect actors from the South have responded to the displacement of refugees from Syria. The main research aims are: 1. identifying diverse models of Southern-led responses to conflict-induced displacement, 2. examining the (un)official motivations, nature and implications of Southern-led responses, 3. examining refugees’ experiences and perceptions of Southern-led responses, 4. exploring diverse Southern and Northern actors’ perceptions of Southern-led responses, 5. tracing the implications of Southern-led initiatives for humanitarian theory and practice. Based on a critical theoretical framework inspired by post-colonial and feminist approaches, the project contributes to theories of humanitarianism and debates regarding donor-recipient relations and refugees’ agency in displacement situations. It will also inform the development of policies to most appropriately address refugees’ needs and rights. This highly topical and innovative project thus has far-reaching implications for refugees and local communities, academics, policy-makers and practitioners.

ATM is the protein kinase that is mutated in the hereditary autosomal recessive disease ataxia telangiectasia (A-T). A-T patients display immune deficiencies, cancer predisposition and radiosensitivity. The molecular role of ATM is to respond to DNA damage by phosphorylating its substrates, thereby promoting repair of damage or arresting the cell cycle. Following the induction of double-strand breaks (DSBs), the NBS1 protein is required for activation of ATM. But ATM can also be activated in the absence of DNA damage. Treatment of cultured cells with hypotonic stress leads to the activation of ATM, presumably due to changes in chromatin structure. We have recently described a second ATM cofactor, ATMIN (ATM INteractor). ATMIN is dispensable for DSBs-induced ATM signalling, but ATM activation following hypotonic stress is mediated by ATMIN. While the biological role of ATM activation by DSBs and NBS1 is well established, the significance, if any, of ATM activation by ATMIN and changes in chromatin was up to now completely enigmatic. ATM is required for class switch recombination (CSR) and the suppression of translocations in B cells. In order to determine whether ATMIN is required for any of the physiological functions of ATM, we generated a conditional knock-out mouse model for ATMIN. ATM signaling was dramatically reduced following osmotic stress in ATMIN-mutant B cells. ATMIN deficiency led to impaired CSR, and consequently ATMIN-mutant mice developed B cell lymphomas. Thus ablation of ATMIN resulted in a severe defect in ATM function. Our data strongly argue for the existence of a second NBS1-independent mode of ATM activation that is physiologically relevant. While a large amount of scientific effort has gone into characterising ATM signaling triggered by DSBs, essentially nothing is known about NBS1-independent ATM signaling. The experiments outlined in this proposal have the aim to identify and understand the molecular pathway of ATMIN-dependent ATM signaling.

It has long been understood that genes contribute to phenotypes that are then the basis of selection. However, the nature and process of this relationship remains largely theoretical, and the relative contribution of change in gene expression and coding sequence to phenotypic diversification is unclear. The aim of this proposal is to fuse information about sexually dimorphic phenotypes, the mating systems and sexually antagonistic selective agents that shape sexual dimorphism, and the sex-biased gene expression patterns that encode sexual dimorphisms, in order to create a cohesive integrated understanding of the relationship between evolution, the genome, and the animal form. The primary approach of this project is to harnesses emergent DNA sequencing technologies in order to measure evolutionary change in gene expression and coding sequence in response to different sex-specific selection regimes in a clade of birds with divergent mating systems. Sex-specific selection pressures arise in large part as a consequence of mating system, however males and females share nearly identical genomes, especially in the vertebrates where the sex chromosomes house very small proportions of the overall transcriptome. This single shared genome creates sex-specific phenotypes via different gene expression levels in females and males, and these sex-biased genes connect sexual dimorphisms, and the sexually antagonistic selection pressures that shape them, with the regions of the genome that encode them. The Galloanserae (fowl and waterfowl) will be used to in the proposed project, as this clade combines the necessary requirements of both variation in mating systems and a well-conserved reference genome (chicken). The study species selected from within the Galloanserae for the proposal exhibit a range of sexual dimorphism and sperm competition, and this will be exploited with next generation (454 and Illumina) genomic and transcriptomic data to study the gene expression patterns that underlie sexual dimorphisms, and the evolutionary pressures acting on them. This work will be complemented by the development of mathematical models of sex-specific evolution that will be tested against the gene expression and gene sequence data in order to understand the mechanisms by which sex-specific selection regimes, arising largely from mating systems, shape the phenotype via the genome.

The project will examine the histories of yoga, ayurveda and rasashastra (Indian alchemy and iatrochemistry) from the tenth century to the present, focussing on the disciplines' health, rejuvenation and longevity practices. The goals of the project are to reveal the entanglements of these historical traditions, and to trace the trajectories of their evolution as components of today's global healthcare and personal development industries. Our hypothesis is that practices aimed at achieving health, rejuvenation and longevity constitute a key area of exchange between the three disciplines, preparing the grounds for a series of important pharmaceutical and technological innovations and also profoundly influencing the discourses of today's medicalized forms of globalized yoga as well as of contemporary institutionalized forms of ayurveda and rasashastra. Drawing upon the primary historical sources of each respective tradition as well as on fieldwork data, the research team will explore the shared terminology, praxis and theory of these three disciplines. We will examine why, when and how health, rejuvenation and longevity practices were employed; how each discipline’s discourse and practical applications relates to those of the others; and how past encounters and cross-fertilizations impact on contemporary health-related practices in yogic, ayurvedic and alchemists’ milieus. The five-year project will be based at the Department of South Asian, Tibetan and Buddhist Studies at Vienna University and carried out by an international team of 3 post-doctoral researchers. The research will be grounded in the fields of South Asian studies and social history. An international workshop and an international conference will be organized to present and discuss the research results, which will also be published in peer-reviewed journals, an edited volume, and in individual monographs. A project website will provide open access to all research results.

The proposed research entails an ethnographic study of two contemporary cases of post-conflict reconciliation: one, the Bosnian case, where international intervention ended conflict in a stalemate and went on to instigate a decade-long process of transition; and the other, the Spanish case, where a nationally-contrived pact of silence introduced an overnight transition after Franco's death a pact now being broken nearly seventy years after the country's civil war concluded. Both societies witnessed massive violations of international humanitarian law. Both societies are presently exhuming, identifying and re-burying their dead. But their trajectories of transitional justice could not have been more different. This project will investigate how Law shapes cultural memories of wartime atrocity in these contrasting scenarios. How do criminal prosecutions, constitutional reforms, and international rights mechanisms, provide or obfuscate the scales into which histories of violent conflict are framed? Does the systematic re-structuring of legislative and judicial infrastructure stifle recognition of past abuses or does it create the conditions through which such pasts can be confronted? How does Law shape or inflect the cultural politics of memory and memorialisation? And most importantly, how should legal activity be weighted, prioritised and sequenced with other, extra-legal components of peace-building initiatives? The ultimate goal of this project will be to mobilise the findings from the two field-sites to suggest a more nuanced assessment of Law s place in transitional justice. Arguing that disparate historical, cultural and legal contexts require equally distinct approaches towards social healing, the research aims to produce a Post-Conflict Action Framework an architecture of questions and concerns, which, once answered, would point towards context-specific designs for transitional justice programmes in the future.

Learning from others is fundamental to ecological success across the animal kingdom, but a key theme to emerge from recent research is that individuals respond differently to social information. Understanding this diversity is an imposing challenge, because it is hard to replicate the overwhelming complexity of free-living groups within controlled laboratory conditions. Yet here I propose that one of the most complex social models that we know of— the sophisticated eusocial societies of honeybees— offer unrivaled and yet unrecognized potential to study social information flow through a natural group. The honeybee “dance language” is one of the most celebrated communication systems in the animal world, and central to a powerful information network that drives our most high-profile pollinator to food, but bee colonies are uniquely tractable for two reasons. Firstly, next-generation transcriptomics could allow us to delve deep into this complexity at the molecular level, on a scale that is simply not available in vertebrate social systems. I propose to track information flow through a natural group using brain gene expression profiles, to understand how dances elicit learning in the bee brain. Secondly, although bee foraging ranges are vast and diverse, social learning takes place in one centralized location (the hive). The social sciences now offer powerful new tools to analyze social networks, and I will use a cutting-edge network-based modelling approach to understand how the importance of social learning mechanisms shifts with ecology. In the face of global pollinator decline, understanding the contribution of foraging drivers to colony success has never been more pressing, but the importance of the dance language reaches far beyond food security concerns. This research integrates proximate and ultimate perspectives to produce a comprehensive, multi-disciplinary program; a high-risk, high-gain journey into new territory for understanding animal communication.

This project investigates the cross-fertilisation of Anglo/American and German literature and film during the Allied Occupation of Germany. It will be the first study to survey the cultural landscape of the British and American zones of Occupied Germany in any detail. By doing so it will offer a new interpretative framework for postwar culture, in particular in three areas: the history of the Allied Occupation of Germany; the history of postwar Anglophone and Germanophone literature (arguing the two were more intertwined than has previously been suggested); and the history of the relationship between postwar and Cold War. Combining Anglo-American and German literature and film history with critical analysis, cultural history and life-writing, this is a necessarily ambitious, multidisciplinary study which will open up a major new field of research.

According to the European Commission, to design effective policies for ensuring a “more dynamic, innovative and competitive” economy, it is essential to understand the decision-making process of firms as they differ a lot in terms of their capacities and policy responses (EC 2007). The objective of my future research is to provide such an analysis. BIGlobal will examine the sources of firm growth and market power to provide new insights into welfare and policy in a globalized world. Much of analysis of the global economy is set in the paradigm of markets that allocate resources efficiently and there is little role for policy. But big firms dominate economic activity, especially across borders. How do firms grow and what is the effect of their market power on the welfare impact of globalization? This project will determine how firm decisions matter for the aggregate gains from globalization, the division of these gains across different individuals and their implications for policy design. Over the next five years, I will incorporate richer firms behaviour in models of international trade to understand how trade and industrial policies impact the growth process, especially in less developed markets. The specific questions I will address include: how can trade and competition policy ensure consumers benefit from globalization when firms engaged in international trade have market power, how do domestic policies to encourage agribusiness firms affect the extent to which small farmers gain from trade, how do industrial policies affect firm growth through input linkages, and what is the impact of banking globalization on the growth of firms in the real sector. Each project will combine theoretical work with rich data from developing economies to expand the frontier of knowledge on trade and industrial policy, and to provide a basis for informed policymaking.

This research project investigates the dynamics of private and public property in contemporary biomedical research. It will develop an analytical framework combining insights from science and technology studies, economic sociology, and legal and political philosophy, and pursues a social scientific investigation of the evolution of intellectual property rights in three fields of bioscientific research: 1) the use of transgenic research mice; 2) the legal status of totipotent and pluripotent stem cell lines; and 3) modes of collaboration for research and development on neglected diseases. These three domains, and their attendant modes of appropriation, will be compared across three general research themes: a) the production of public scientific goods; b) categories of appropriation; and c) the moral economy of research. The project rests on close observation of research practices in these three domains. The BioProperty research programme will track the trajectories of property rights and property objects in each of the three fields of biomedical research.

Iridescence is a form of structural colour which changes hue according to the angle from which it is viewed. Blue iridescence caused by multilayers has been described on the leaves of taxonomically diverse species such as the lycophyte Selaginella uncinata and the angiosperm Begonia pavonina. While much is known about the role of leaf pigment colour, the adaptive role of leaf iridescence is unknown. Hypotheses have been put forward including 1) iridescence acts as disruptive camouflage against herbivores 2) it enhances light sensing and capture in low light conditions 3) it is a photoprotective mechanism to protect shade-adapted plants against high light levels. These hypotheses are not mutually exclusive: each function may be of varying importance in different environments. To understand any one function, we need a interdisciplinary approach considering all three potential functions and their interactions. The objective of my research would be to test these hypotheses, using animal behavioural and plant physiological methods, to determine the functions of leaf iridescence and how the plant has adapted to the reflection of developmentally vital wavelengths. Use of molecular and bioinformatics methods will elucidate the genes that control the production of this potentially multifunctional optical phenomenon. This research will provide a pioneering study into the generation, developmental impact and adaptive significance of iridescence in leaves. It would also answer questions at the frontiers of several fields including those of plant evolution, insect vision, methods of camouflage, the generation and role of animal iridescence, and could also potentially inspire synthetic biomimetic applications.

"The body is ubiquitous in perceptual experience and is central to our sense of self and personal identity. Disordered body representations are central to several serious psychiatric and neurological disorders. Thus, identifying factors which contribute to the formation and maintenance of body representations is crucial for understanding how body representation goes awry in disease, and how it might be corrected by potential novel therapeutic interventions. Several types of sensory signals provide information about the body, making the body the multisensory object, par excellence. Little is known, however, about how information from somatosensation and from vision is integrated to construct the rich body representations we all experience. This project fills this gap in current understanding by determining how the brain builds body representations (BODYBUILDING). A hierarchical model of body representation is proposed, providing a novel theoretical framework for understanding the diversity of body representations and how they interact. The key motivating hypothesis is that body representation is determined by the dialectic between two major cognitive processes. First, from the bottom-up, somatosensation represents the body surface as a mosaic of discrete receptive fields, which become progressively agglomerated into larger and larger units of organisation, a process I call fusion. Second, from the top-down, vision starts out depicting the body as an undifferentiated whole, which is progressively broken into smaller parts, a process I call segmentation. Thus, body representation operates from the bottom-up as a process of fusion of primitive elements into larger complexes, as well as from the top-down as a process of segmentation of an initially undifferentiated whole into more basic parts. This project uses a combination of psychophysical, electrophysiological, and neuroimaging methods to provide fundamental insight into how we come to represent our body."

"Conscious experiences normally result from the flow of external input into our sensory systems. However, our minds are also able to create conscious percepts in the absence of any sensory stimulation; these internally generated percepts are referred to as mental images, and they have many similarities with real visual percepts; consequently, mental imagery is often referred to as “seeing in the mind’s eye”. Mental imagery is also believed to be closely related to working memory, a mechanism which can maintain “offline” representations of visual stimuli no longer in the observer’s view, as both involve internal representations of previously seen visual attributes. Indeed, visual imagery is often thought of as a conscious window into the content of memory representations. Imagery, working memory, and conscious perception are thus thought to rely on very similar mechanisms. However, in everyday life we are generally able to keep apart the constructs of our imagination from real physical events; this begs the question of how the brain distinguishes internal mental images from externally induced visual percepts. To answer this question, the proposed work aims to isolate the cortical mechanisms associated uniquely with WM and imagery independently of each other and independently of the influence of external conscious percepts. Furthermore, by the use of neuroimaging and brain stimulation, we aim to determine the cortical mechanisms which keep apart internally generated and externally induced percepts, in both health and disease. This is a question of great clinical interest, as the ability to distinguish the perceived from the imagined is impoverished in psychotic disorders. In addition to revealing the mechanisms underlying this confusion, the present project aims to alleviate it in psychotic patients by the use of brain stimulation. The project will thus significantly improve our understanding of these cognitive processes and will also have clinical implications."

We are currently witnessing a paradigm shift in our understanding of human brain function, moving towards a clearer description of cortical processing. Sensory systems are no longer considered as 'passively recording' but rather as dynamically anticipating and adapting to the rapidly changing environment. These new ideas are encompassed in the predictive coding framework, and indeed in a unifying theory of the brain (Friston, 2010). In terms of brain computation, a predictive model is created in higher cortical areas and communicated to lower sensory areas through feedback connections. Based on my pioneering research I propose experiments that are capable of ‘brain-reading’ cortical feedback– which would contribute invaluable data to theoretical frameworks. The proposed research project will advance our understanding of ongoing brain activity, contextual processing, and cortical feedback - contributing to what is known about general cortical functions. By providing new insights as to the information content of cortical feedback, the proposal will fill one of the most important gaps in today’s knowledge about brain function. Friston’s unifying theory of the brain (Friston, 2010) and contemporary models of the predictive-coding framework (Hawkins and Blakeslee, 2004;Mumford, 1992;Rao and Ballard, 1999) assign feedback processing an essential role in cortical processing. Compared to feedforward information processing, our knowledge about feedback processing is in its infancy. The proposal introduces parametric and explorative brain reading designs to investigate this feedback processing. The chief goal of my proposal will be precision measures of cortical feedback, and a more ambitious objective is to read mental images and inner thoughts.

Music and language share similar properties and are processed in overlapping brain regions. As a common information-bearing element in music and language, pitch plays an essential role in encoding musical melodies, signifying linguistic functions, and conveying emotions through music and speech. However, two distinct neurodevelopmental disorders, congenital amusia (CA) and autism spectrum disorders (ASD), affecting millions of people in Europe and worldwide, may selectively impair individuals’ ability to process musical, linguistic, and emotional pitch. To date, it remains unclear why individuals with CA and ASD exhibit significant differences in music, speech, and emotion processing. Under our Delicate Form-Function Balance Hypothesis, we will conduct a series of behavioural and neurophysiological experiments to test the central hypothesis that normal musical, linguistic, and emotional functioning requires a delicate balance in the encoding and decoding of form and function in musical, speech, and emotional communication, with musical communication centred on form and linguistic and emotional communication focused on function. Most critically, we hypothesize that the differences in music, speech, and emotional processing in CA and ASD are rooted not only in pitch and cognitive abilities, but also in the balance between form and function for each domain. Addressing three specific aims regarding the impacts of cognitive processing styles, pitch processing skills, and language background (tone vs. non-tonal) on the behavioural and neurophysiological characteristics of music, language, and emotion processing in CA and ASD, this research will not only help reveal the underlying mechanisms of the two defining aspects of human cognition, music and language, but also form a laboratory for testing key hypotheses about the bio-behavioural manifestations of human neurodevelopmental disorders in music and language processing.

Cancer screening and the diagnostics industry: a comparative analysis of the political economy of diagnostic innovation A decade after the Human Genome Project, major public and private investments continue to fuel expectations of a genomic revolution in biomedicine. The freight of expectations surrounding the new “age of diagnostics” is accompanied by much uncertainty about how public policy should steer diagnostic innovation, with much debate about inter alia the harms of creating diagnostic monopolies through gene patenting, and the risks of under- or over-regulation. However, due to the paucity of research on diagnostic innovation, policy deliberation is driven more by anecdote and expert opinion than empirical evidence. With a specific focus on screening/early detection of cancer, this project will map industry dynamics, technological trajectories and regulatory developments in Europe and the USA from 1996 to the present day. Combining quantitative and qualitative methods, the project’s innovative dimensions include a new conceptual model of socio-technical transition in the diagnostics sector, and the first integrative analysis linking scientometric data on the interactions between public and private actors in the diagnostic research domain with comparative transnational analysis of regulatory decision-making. Through a novel integration of conceptual insights from the literature on biomedicalisation and scholarship on socio-technical regime change, this project aims to advance both fields of research by applying a new multi-scale, multi-level model of socio-technical transition. The project will provide unprecedented insight into the factors shaping the development of a new generation of molecular diagnostic tests, and examine how these technologies are reconfiguring disease categories and redrawing the boundaries between health and sickness. We will establish a platform of theory and methods for a broader programme of work on diagnostic innovation.
