WIDER's work on bovine TB in the news
The publication earlier this month in Nature by Ellen Brooks Pollock (Cambridge), Gareth Roberts (Statistics) and Matt Keeling (Mathematics and Life Sciences) of their joint paper has stirred up a great deal of interest not just in the scientific community but also the daily newspapers and BBC TV news.
This work was begun in 2008 and follows on from other successful research at Warwick and Cambridge on both bovine TB and modelling livestock infections. This is the first time that anyone has developed a mechanistic mathematical national-scale model for the spread of bovine TB that accounts for multiple routes of transmission and allows the impact of different controls to be tested.
Their model shows that transmission is complex and multifaceted – with cattle-to-cattle transmission, failure to detect infection, movement of infected animals and transmission from the environment all playing a role. The authors believe it is this complexity that continues to fuel scientific and public debate about bovine TB.

Karen Vogtmann wins the Humboldt Research Prize
The award is granted in recognition of a researcher's lifetime achievements to academics whose fundamental discoveries, new theories, or insights have had a significant impact on their own discipline and who are expected to continue producing cutting-edge achievements in the future. Vogtmann was cited as an internationally renowned leader in the rapidly growing field of geometric group theory, who has made important contributions to our understanding of the automorphism groups of free groups. The introduction of what came to be known as Culler–Vogtmann space or “outer space” opened the way for a geometric study of these groups and their homology. In Germany, she will investigate combinatorial boundaries for outer space as well as instances of the Farrell–Jones conjecture.

Three Warwick Mathematicians win LMS prizes
Professor Miles Reid FRS is awarded a PÓLYA PRIZE for his exceptionally creative work on higher dimensional algebraic geometry; in particular, on canonical singularities, the MacKay correspondence, the explicit study of 3-dimensional flips, the structure of Gorenstein rings, and for his inspired expositions.
From the citation: Miles Reid has done fundamental work on surfaces of general type with low invariants; he invented terminal and canonical singularities, in work that revolutionised the field of higher dimensional algebraic geometry; he extended the McKay correspondence to higher dimensions; he is making pioneering discoveries in the structure theory of Gorenstein rings in codimension 4 and higher; he is advancing a monumental project of classification of 3-fold flips. In his research work, Reid has often been a pioneer, often years ahead of his time.
Professor Martin Hairer FRS is awarded a FRÖHLICH PRIZE for his work on the interface between probability theory and partial differential equations.
From the citation: Martin Hairer’s recent research is regarded as having revolutionized an entire field of research lying between probability theory and partial differential equations. His theory of regularity structures provides a mathematical framework in which it is possible to formulate and understand a number of equations describing the temporal evolutions of certain random systems exhibiting large-scale fluctuations. In particular, it gives a solution theory for the KPZ equation and for the dynamical $\Phi^4_3$ model.
Professor Caroline Series is awarded a SENIOR ANNE BENNETT PRIZE in recognition of her leading contributions to hyperbolic geometry and symbolic dynamics, and of the major impact of her numerous initiatives towards the advancement of women in mathematics. Caroline Series is the first winner of the SENIOR ANNE BENNETT PRIZE which is awarded in memory of Anne Bennett, a gifted scientific administrator who died suddenly whilst working for the Society.
Caroline Series’ research concerns intricate and fundamental questions about the geometry of surfaces and 3-manifolds. Besides groundbreaking research, her wide ranging contributions to the community of mathematicians include a distinguished record of relentless effort in encouraging women mathematicians, both as a founder member of European Women in Mathematics and in many subsequent initiatives.

Oleg Zaboronski awarded Leverhulme Research Fellowship
Exactly solvable agent-based (particle) models are of great interest in physics, biology and economics. For many such models, the statistical behaviour is universal and described by large random matrices. There is evidence that a fundamental particle system (Brownian particles killing each other or coagulating on contact) is also related to random matrices (populated with independent Brownian motions). The aim of the proposed research is to pin this relation down and generalize to more elaborate particle systems. Reaching this aim requires solution to a long-standing problem of dynamic correlations in random matrix theory thus advancing our understanding of stochastic processes associated with random matrices.

Karen Vogtmann wins a Royal Society Wolfson Research Merit award
Groups are algebraic objects that encode symmetry, which explains why they are fundamental to all of mathematics and the physical sciences. Groups themselves have symmetries called automorphisms, and the simplest groups often have the most complex and interesting autoorphism groups. Professor Vogtmann works on developing geometric tools for studying such automorphism groups. This specific project concentrates on outer automorphism groups of free groups and more generally of right-angled Artin groups, a class of groups particularly relevant to recent breakthroughs in 3-manifold topology.
The awards, which are administered by the Royal Society, are jointly funded by the Wolfson Foundation and the Department for Business, Innovation and Skills (BIS); the scheme aims to provide universities with additional support to enable them to attract science talent from overseas and to retain respected UK scientists of outstanding achievement and potential.

Martin Hairer elected Fellow of the Royal Society
Professor Martin Hairer is one of the world's foremost leaders in the field of stochastic partial differential equations in particular, and in stochastic analysis and stochastic dynamics in general. By bringing new ideas to the subject he made fundamental advances in many important directions such as the study of variants of Hormander's theorem, systematisation of the construction of Lyapunov functions for stochastic systems, development of a general theory of ergodicity for non-Markovian systems, multiscale analysis techniques, theory of homogenisation, theory of path sampling and, most recently, theory of rough paths and the newly introduced theory of regularity structures.

Filip Rindler awarded EPSRC Fellowship
Filip Rindler, a Warwick Zeeman Lecturer, has been awarded a 3-year EPSRC Fellowship to investigate Singularities in Nonlinear PDEs which is to start in October 2014 and which includes funding for a related workshop.
This project aims to further the theoretical understanding of singularities, manifested as oscillations and concentrations, in solutions to nonlinear partial differential equations. Since such singularities are not only physically relevant, but also present many technical challenges in the pursuit to prove meaningful assertions about PDEs, this proposal bridges theoretical and applied mathematics. On the applied side, it is related to material microstructure (for example in alloys) and the emergence of complex macroscopic material behaviour from microscopic oscillations. On the theory side, oscillations and concentrations precisely distinguish between weak and strong compactness of sequences in Lebesgue and Sobolev spaces and “quantifying” this difference in a meaningful way is a pivotal goal of this project. Based on recently developed new tools, we aim to improve our understanding of these phenomena and to develop new applications to concrete PDE questions. Collaborations are planned with both applied and theoretical researchers in the field. Furthermore, as part of the grant, a research workshop on the topic will be organised.

Martin Hairer & José Luis Rodrigo win ERC Consolidator grants
The European Research Council (ERC) has awarded two of its new ERC Consolidator Grants to Warwick mathematicians Martin Hairer and José Luis Rodrigo, the only awards in the UK for mathematics. A further two grants were awarded to Warwick in Chemistry. These prestigious new awards will enable already independent excellent researchers to consolidate their own research teams and to develop their most innovative ideas across the European Research Area.
President of the ERC, Professor Jean-Pierre Bourguignon commented: “I am very impressed by the quality of the selected projects. Judging by the ever increasing demand for ERC grants, especially from early- and mid-career researchers, it is clear that funding of this kind is much needed.”
European Commissioner for Research, Innovation and Science Máire Geoghegan-Quinn said: “These researchers are doing ground-breaking work that will advance our knowledge and make a difference to society. The ERC is supporting them at a key moment where funding is often hard to come by: when they need to move forward in their career and develop their own research and teams.”
Martin Hairer's project studies Behaviour near criticality. One of the main challenges of modern mathematical physics is to understand the behaviour of systems at or near criticality. In a number of cases, one can argue heuristically that this behaviour should be described by a nonlinear stochastic partial differential equation. Some examples of systems of interest are models of phase coexistence near the critical temperature, one-dimensional interface growth models, and models of absorption of a diffusing particle by random impurities. Unfortunately, the equations arising in all of these contexts are mathematically ill-posed to the extent that they defeat all current stochastic PDE techniques.
Recently, the theory of regularity structures has allowed us to give a rigorous mathematical interpretation to such equations and to build the mathematical objects conjectured to describe the above-mentioned systems near criticality. The aim of the proposal is to study the convergence of a variety of concrete microscopic models to these limiting objects. The project will yield unique insight in the large-scale behaviour of a number of physically relevant systems in regimes where both nonlinear effects and random fluctuations compete with equal strength.
José Luis Rodrigo's project concerns 3D Euler, Vortex Dynamics and PDE which deals with a collection of problems in analysis and partial differential equations arising from fluid mechanics. In particular, the main equation under consideration is the three dimensional Euler equation (for the evolution of an incompressible, inviscid fluid). Main objectives include the understanding of the evolution of isolated vortex lines for this equation, and the construction and understanding of the geometry and evolution of highly concentrated vortex tubes.
