Summary During the 20th century computer technology evolved from bulky, slow, special purpose mechanical engines to the now ubiquitous silicon chips and software that are one of the pinnacles of human ingenuity. The goal of the field of molecular programming is to take the next leap and build a new generation of matter-based computers using DNA, RNA and proteins. This will be accomplished by computer scientists, physicists and chemists designing molecules to execute ``wet'' nanoscale programs in test tubes. The workflow includes proposing theoretical models, mathematically proving their computational properties, physical modelling and implementation in the wet-lab.
The past decade has seen remarkable progress at building static 2D and 3D DNA nanostructures. However, unlike biological macromolecules and complexes that are built via specified self-assembly pathways, that execute robotic-like movements, and that undergo evolution, the activity of human-engineered nanostructures is severely limited. We will need sophisticated algorithmic ideas to build structures that rival active living systems. Active-DNA, aims to address this challenge by achieving a number of objectives on computation, DNA-based self-assembly and molecular robotics. Active-DNA research work will range from defining models and proving theorems that characterise the computational and expressive capabilities of such active programmable materials to experimental work implementing active DNA nanostructures in the wet-lab.

Project From the earliest modern humans to the onset of farming (45,000-4,500 BP): the role of climate, life-style, health, migration and selection in shaping European population history
Researcher (PI) Ron Pinhasi
Host Institution (HI) UNIVERSITY COLLEGE DUBLIN, NATIONAL UNIVERSITY OF IRELAND, DUBLIN
Call Details Starting Grant (StG), SH6, ERC-2010-StG_20091209
Summary The colonisation of Europe by anatomically modern humans (AMHs) ca. 45,000 years before present (BP) and the transition to farming ca. 8,000 BP are two major events in human prehistory. Both events involved certain cultural and biological adaptations, technological innovations, and behavioural plasticity which are unique to our species. The reconstruction of these processes and the causality between them has so far remained elusive due to technological, methodological and logistical complexities. Major developments in our understanding of the anthropology of the Upper Palaeolithic, Mesolithic and Neolithic, and advances in ancient DNA (aDNA) technology and chronometric methods now allow us to assess in sufficient resolution the interface between these evolutionary processes, and changes in human culture and behaviour.
The proposed research will investigate the complex interface between the morphological, genetic, behavioural, and cultural factors that shaped the population history of European AMHs. The PI s interdisciplinary expertise in these areas, his access to and experience of relevant skeletal collections, and his ongoing European collaborations will allow significant progress in addressing these fundamental questions. The approach taken will include (a) the collection of bioarchaeological, aDNA, stable isotope (for the analysis of ancient diet) and radiometric data on 500 skeletons from key sites/phases in Europe and western Anatolia, and (b) the application of existing and novel aDNA, bioarchaeological and simulation methodologies. This research will yield results that transform our current understanding of major demographic and evolutionary processes and will place Europe at the forefront of anthropological biological and genetic research.

Project Alpha Shape Theory Extended
Researcher (PI) Herbert Edelsbrunner
Host Institution (HI) INSTITUTE OF SCIENCE AND TECHNOLOGYAUSTRIA
Call Details Advanced Grant (AdG), PE6, ERC-2017-ADG
Summary Alpha shapes were invented in the early 80s of last century, and their implementation in three dimensions in the early 90s was at the forefront of the exact arithmetic paradigm that enabled fast and correct geometric software. In the late 90s, alpha shapes motivated the development of the wrap algorithm for surface reconstruction, and of persistent homology, which was the starting point of rapidly expanding interest in topological algorithms aimed at data analysis questions.
We now see alpha shapes, wrap complexes, and persistent homology as three aspects of a larger theory, which we propose to fully develop. This viewpoint was a long time coming and finds its clear expression within a generalized
version of discrete Morse theory. This unified framework offers new opportunities, including
(I) the adaptive reconstruction of shapes driven by the cavity structure;
(II) the stochastic analysis of all aspects of the theory;
(III) the computation of persistence of dense data, both in scale and in depth;
(IV) the study of long-range order in periodic and near-periodic point configurations.
These capabilities will significantly deepen as well as widen the theory and enable new applications in the sciences. To gain focus, we concentrate on low-dimensional applications in structural molecular biology and particle systems.

Project Medicine, Immortality, Moksha: Entangled Histories of Yoga, Ayurveda and Alchemy in South Asia
Researcher (PI) Dagmar Wujastyk
Host Institution (HI) UNIVERSITAT WIEN
Call Details Starting Grant (StG), SH6, ERC-2014-STG
Summary 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.

Project Big Splash: Efficient Simulation of Natural Phenomena at Extremely Large Scales
Researcher (PI) Christopher John Wojtan
Host Institution (HI) Institute of Science and Technology Austria
Call Details Starting Grant (StG), PE6, ERC-2014-STG
Summary Computational simulations of natural phenomena are essential in science, engineering, product design, architecture, and computer graphics applications. However, despite progress in numerical algorithms and computational power, it is still unfeasible to compute detailed simulations at large scales. To make matters worse, important phenomena like turbulent splashing liquids and fracturing solids rely on delicate coupling between small-scale details and large-scale behavior. Brute-force computation of such phenomena is intractable, and current adaptive techniques are too fragile, too costly, or too crude to capture subtle instabilities at small scales. Increases in computational power and parallel algorithms will improve the situation, but progress will only be incremental until we address the problem at its source.
I propose two main approaches to this problem of efficiently simulating large-scale liquid and solid dynamics. My first avenue of research combines numerics and shape: I will investigate a careful de-coupling of dynamics from geometry, allowing essential shape details to be preserved and retrieved without wasting computation. I will also develop methods for merging small-scale analytical solutions with large-scale numerical algorithms. (These ideas show particular promise for phenomena like splashing liquids and fracturing solids, whose small-scale behaviors are poorly captured by standard finite element methods.) My second main research direction is the manipulation of large-scale simulation data: Given the redundant and parallel nature of physics computation, we will drastically speed up computation with novel dimension reduction and data compression approaches. We can also minimize unnecessary computation by re-using existing simulation data. The novel approaches resulting from this work will undoubtedly synergize to enable the simulation and understanding of complicated natural and biological processes that are presently unfeasible to compute.

Project Foundations and Tools for Client-Side Web Security
Researcher (PI) Matteo MAFFEI
Host Institution (HI) TECHNISCHE UNIVERSITAET WIEN
Call Details Consolidator Grant (CoG), PE6, ERC-2017-COG
Summary The constantly increasing number of attacks on web applications shows how their rapid development has not been accompanied by adequate security foundations and demonstrates the lack of solid security enforcement tools. Indeed, web applications expose a gigantic attack surface, which hinders a rigorous understanding and enforcement of security properties. Hence, despite the worthwhile efforts to design secure web applications, users for a while will be confronted with vulnerable, or maliciously crafted, code. Unfortunately, end users have no way at present to reliably protect themselves from malicious applications.
BROWSEC will develop a holistic approach to client-side web security, laying its theoretical foundations and developing innovative security enforcement technologies. In particular, BROWSEC will deliver the first client-side tool to secure web applications that is practical, in that it is implemented as an extension and can thus be easily deployed at large, and also provably sound, i.e., backed up by machine-checked proofs that the tool provides end users with the required security guarantees. At the core of the proposal lies a novel monitoring technique, which treats the browser as a blackbox and intercepts its inputs and outputs in order to prevent dangerous information flows. With this lightweight monitoring approach, we aim at enforcing strong security properties without requiring any expensive and, given the dynamic nature of web applications, statically infeasible program analysis.
BROWSEC is thus a multidisciplinary research effort, promising practical impact and delivering breakthrough advancements in various disciplines, such as web security, JavaScript semantics, software engineering, and program verification.

Summary Through animal domestication humans profoundly altered their relationship with nature, controlling the breeding of their major food sources for material, social or symbolic profit. Understanding this complex process is a compelling research aim. There is a need to develop new high-resolution genetic tools to put flesh on the bones of this two-millenium long transition. These will take advantage of very recent advances: targeted next generation DNA sequencing, high throughput screening of expertly provenanced archaeological samples, and emerging knowledge of modern cattle, sheep and goat genome science plus their genetic geographies. Combining these, this proposal will develop an ancient DNA data matrix that will be unparalleled in archaeological science. These data will unlock the key genetic changes that accompany the domestic state and the breeding structures that are a consequence of human management. It will also identify the wild and proto-domestic populations that later herds emerge from. A more precise geography and timing of the key changes will enable richer contextualising inform our assessement of why these changes take place. The 10,000 year matrix for each species will function as a standard spatiotemporal reference grid on which any subsequent bone or animal artefact may be placed i.e. via genetic postcoding. Exceptional discontinuities in the matrix will highlight points of strong historical interest such as the emergence of new trade networks, migrations and periods of economic turbulence - perhaps driven by climate fluctuations or plagues. The final work objectives will focus on diachronic sample assemblages selected to have particular import for both historical events and transitions in material culture. For example, manuscript vellum samples will give a uniquely dated series that will enable correlation of genetic change with historical studies of the timing and impact of past animal plagues (e.g. in C 14th and C 18th Europe).

Project The Parameterized Complexity of Reasoning Problems
Researcher (PI) Stefan Szeider
Host Institution (HI) TECHNISCHE UNIVERSITAET WIEN
Call Details Starting Grant (StG), PE6, ERC-2009-StG
Summary Reasoning, to derive conclusions from facts, is a fundamental task in Artificial Intelligence, arising in a wide range of applications from Robotics to Expert Systems. The aim of this project is to devise new efficient algorithms for real-world reasoning problems and to get new insights into the question of what makes a reasoning problem hard, and what makes it easy. As key to novel and groundbreaking results we propose to study reasoning problems within the framework of Parameterized Complexity, a new and rapidly emerging field of Algorithms and Complexity. Parameterized Complexity takes structural aspects of problem instances into account which are most significant for empirically observed problem-hardness. Most of the considered reasoning problems are intractable in general, but the real-world context of their origin provides structural information that can be made accessible to algorithms in form of parameters. This makes Parameterized Complexity an ideal setting for the analysis and efficient solution of these problems. A systematic study of the Parameterized Complexity of reasoning problems that covers theoretical and empirical aspects is so far outstanding. This proposal sets out to do exactly this and has therefore a great potential for groundbreaking new results. The proposed research aims at a significant impact on the research culture by setting the grounds for a closer cooperation between theorists and practitioners.

Project Getting at the Heart of Things: Towards Expressivity-aware Computer Systems in Music
Researcher (PI) Gerhard Widmer
Host Institution (HI) UNIVERSITAT LINZ
Call Details Advanced Grant (AdG), PE6, ERC-2014-ADG
Summary What makes music so important, what can make a performance so special and stirring? It is the things the music expresses, the emotions it induces, the associations it evokes, the drama and characters it portrays. The sources of this expressivity are manifold: the music itself, its structure, orchestration, personal associations, social settings, but also – and very importantly – the act of performance, the interpretation and expressive intentions made explicit by the musicians through nuances in timing, dynamics etc.
Thanks to research in fields like Music Information Research (MIR), computers can do many useful things with music, from beat and rhythm detection to song identification and tracking. However, they are still far from grasping the essence of music: they cannot tell whether a performance expresses playfulness or ennui, solemnity or gaiety, determination or uncertainty; they cannot produce music with a desired expressive quality; they cannot interact with human musicians in a truly musical way, recognising and responding to the expressive intentions implied in their playing.
The project is about developing machines that are aware of certain dimensions of expressivity, specifically in the domain of (classical) music, where expressivity is both essential and – at least as far as it relates to the act of performance – can be traced back to well-defined and measurable parametric dimensions (such as timing, dynamics, articulation). We will develop systems that can recognise, characterise, search music by expressive aspects, generate, modify, and react to expressive qualities in music. To do so, we will (1) bring together the fields of AI, Machine Learning, MIR and Music Performance Research; (2) integrate theories from Musicology to build more well-founded models of music understanding; (3) support model learning and validation with massive musical corpora of a size and quality unprecedented in computational music research.

Summary The chronology of ancient Egypt is a golden thread for the memory of early civilisation. It is not only the scaffolding of four millennia of Egyptian history, but also one of the pillars of the chronology of the entire ancient Near East and eastern Mediterranean. The basic division of Egyptian history into 31 dynasties was introduced by Manetho, an Egyptian historian (c. 280 BC) writing in Greek for the Ptolemaic kings. Despite the fact that this scheme was adopted by Egyptologists 200 years ago and remains in use until today, there has never been an in-depth analysis of Manetho’s kinglist and of the names in it. Until now, identifying the Greek renderings of royal names with their hieroglyphic counterparts was more or less educated guesswork. It is thus essential to introduce the principles of textual criticism, to evaluate royal names on a firm linguistic basis and to provide for the first time ever an Egyptological commentary on Manetho’s kinglist. Just like Manetho did long ago, now it is necessary to gather all inscriptional evidence on Egyptian history: dated inscriptions, biographic and prosopographic data of royalty and commoners, genuine Egyptian kinglists and annals. These data must be critically evaluated in context, their assignment to specific reigns must be reconsidered, and genealogies and sequences of officials must be reviewed. The results are not only important for Egyptian historical chronology and for our understanding of the Egyptian perception of history, but also for the interpretation of chronological data gained from archaeological excavations (material culture) and sciences (14C dates, which are interpreted on the basis of historical chronology, e.g., via ‘Bayesian modelling’). The applicant has already shown the significance of this approach in pilot studies on the pyramid age. Further work in cooperation with international specialists will thus shed new light on ancient sources in order to determine the chronology of early civilisation.
