ERC FUNDED PROJECTS

Naturally occurring optical phenomena attract great attention and transform our ability to study biological processes, with “the discovery and development of the green fluorescent protein (GFP)” (Nobel Prize in Chemistry 2008) being a particularly successful example. Although found only in very few species in nature, most organisms can be genetically programmed to produce the brightly fluorescent GFP molecules. Combined with modern fluorescence detection schemes, this has led to entirely new ways of monitoring biological processes. The applicant now demonstrated a biological laser – a completely novel, living source of coherent light based on a single biological cell bioengineered to produce GFP. Such a laser is intrinsically biocompatible, thus offering unique properties not shared by any existing laser. However, the physical processes involved in lasing from GFP remain poorly understood and so far biological lasers rely on bulky, impractical external resonators for optical feedback. Within this project, the applicant and his team will develop for the first time an understanding of stimulated emission in GFP and related proteins and create an unprecedented stand-alone single-cell biolaser based on intracellular optical feedback. These lasers will be deployed as microscopic and biocompatible imaging probes, thus opening in vivo microscopy to dense wavelength-multiplexing and enabling unmatched sensing of biomolecules and mechanical pressure. The evolutionarily evolved nano-structure of GFP will also enable novel ways of studying strong light-matter coupling and will bio-inspire advances of synthetic emitters. The proposed project is inter-disciplinary by its very nature, bridging photonics, genetic engineering and material science. The applicant’s previous pioneering work and synergies with work on other lasers developed at the applicant’s host institution provide an exclusive competitive edge. ERC support would transform this into a truly novel field of research.

AFRIGOS investigates the process of 'respacing' Africa, a political drive towards regional and continental integration, on the one hand, and the re-casting of Africa's engagement with the global economy, on the other. This is reflected in unprecedented levels of investment in physical and communications infrastructure, and the outsourcing of key functions of Customs, Immigration and security agencies. AFRIGOS poses the question of how far respacing is genuinely forging institutions that are facilitating or obstructing the movement of people and goods; that are enabling or preventing urban and border spaces from being more effectively and responsively governed; and that take into account the needs of African populations whose livelihoods are rooted in mobility and informality. The principal research questions are approached through a comparative study of port cities, border towns and other strategic nodes situated along the busiest transport corridors in East, Central, West and Southern Africa. These represent sites of remarkable dynamism and cosmopolitanism, which reflects their role in connecting African urban centres to each other and to other global cities. AFRIGOS considers how governance 'assemblages' are forged at different scales and is explicitly comparative. It works through 5 connected Streams that address specific questions: 1. AGENDA-SETTING is concerned with policy (re-)formulation. 2. PERIPHERAL URBANISM examines governance in border towns and port cities. 3. BORDER WORKERS addresses everyday governance emerging through the interaction of officials and others who make their livelihoods from the border. 4. CONNECTIVE INFRASTRUCTURE looks as the transformative effects of new technologies. 5. PEOPLE & GOODS IN MOTION traces the passage of people and goods and the regimes of regulation to which they are subjected. AFRIGOS contributes to interdisciplinary research on borderland studies, multi-level governance and the everyday state.

This project is a comparative anthropology of conscience, ethics and human rights. Numerous international human rights documents formally declare their commitment to protect freedom of conscience. But, what is conscience and how do we know it when we see it? How do we distinguish it from self-interest or fanaticism? And what happens when the concept, often associated with a distinct Christian or liberal history, travels across cultural boundaries? The project will examine the cultural conditions under which claims to conscience are made possible, and the types of claims that are most persuasive when doing so. The project addresses these issues through the comparative analysis of three case studies: British pacifists, Sri Lankan activists, and Soviet dissidents. These case studies have been carefully chosen to provide globally significant, but contrasting examples of contests over the implications of claims to conscience. If claims of conscience are often associated with a specifically liberal and Christian tradition, mid-twentieth century Britain can be said to stand at the centre of that tradition. Sri Lanka represents a particularly fraught post-colonial South Asian counterpoint, wracked by nationalist violence, and influenced by ethical traditions associated with forms of Hinduism and Buddhism. Soviet Russia represents a further contrast, a totalitarian regime, where atheism was the dominant ethical language. Finally, the project will return specifically to international human rights institutions, examining the history of the category of conscience in the UN human rights system. This project will be ground breaking, employing novel methods and analytical insights, in order to producing the first comparative analysis of the cultural and political salience of claims of conscience. In doing so, the research aims to transform our understandings of the limits and potentials of attempts to protect freedom of conscience.

Medicinal chemistry requires more efficient and diverse methods for the asymmetric synthesis of chiral scaffolds. Over 60% of the world’s top selling small molecule drug compounds are chiral and, of these, approximately 80% are marketed as single enantiomers. There is a compelling correlation between drug candidate “chiral complexity” and the likelihood of progression to the marketplace. Surprisingly, and despite the tremendous advances made in catalysis over the past several decades, the “chiral complexity” of drug discovery libraries has actually decreased, while, at the same time, for the reasons mentioned above, the “chiral complexity” of marketed drugs has increased. Since the mid-1990s, there has been a notable acceleration of this “complexity divergence”. Consequently, there is now an urgent need to provide efficient processes that directly access privileged chiral scaffolds. It is our philosophy that catalysis holds the key here and new processes should be based upon platforms that can exert control over both absolute and relative stereochemistry. In this proposal we outline the development of a range of N-heteroannulation processes based upon the catalytic generation and trapping of unique or unusual classes of organometallic intermediate derived from transition metal insertion into C-C and C-N sigma-bonds. We will provide a variety of enabling methodologies and demonstrate applicability in flexible total syntheses of important natural product scaffolds. The processes proposed are synthetically flexible, operationally simple and amenable to asymmetric catalysis. Likely starting points, based upon preliminary results, will set the stage for the realisation of aspirational and transformative goals. Through the study of the organometallic intermediates involved here, there is potential to generalise these new catalytic manifolds, such that this research will transcend N heterocyclic chemistry to provide enabling methods for organic chemistry as a whole.
