Professor Ulrike Tillmann (OXFORD)
Prof. Ulrike Tillmann FRS has been at the University of Oxford since 1992.
She is an algebraic topologist, known in particular for her work on Riemann surfaces and the homology of their moduli spaces. She has long standing research interest in homology stability questions. In 2011 she introduced an annual course (with Abramsky) in Computational Algebraic Topology at masters level. In the last year, Tillmann has co-organized four workshops on topological data analysis, as well as an CMI-LMS research school.
She held an EPSRC Advanced Fellowship 1997-2003. She was invited to present at the ICM in 2002 and was a member of the topology subject panel for both the 2010 and 2014 ICMs. In 2008 she was made a Fellow of the Royal Society and received the Bessel Forschungspreis from the Humboldt Gesellschaft. She is an inaugural Fellow of the AMS.
Algebraic topology and its applications. Algebraic topology is a very effective tool to study the global properties of geometric objects. For example, take the surface of a ball and divide it into triangles; now count the number of faces, add the number of vertices and subtract the number of edges; no matter how you choose your triangles, the result will always be 2.
Do the same with the surface of a donut and the result is always 0. These numbers were already known by Euler and are foreshadows of homology developed in the 20th century. By now the basic ideas of algebraic topology have permeated nearly every branch of research in mathematics.
Her research has been motivated by questions in quantum physics and string theory. In particular, she has contributed to understanding of the ‘space of surfaces’.

Professor David Firth (WARWICK)
Professor of Statistics at Warwick and Director of WDSI. Previously Professor of Social Statistics at Oxford. ESRC Professorial Fellow (2003-2006). Fellow of the British Academy (2008). RSS Guy Medals in Bronze (1998) and Silver (2012). John M Chambers Statistical Software Award, 2007. Editor of J Roy Stat Soc B (1998-2001). Publications include three RSS Read Papers and ten R packages.
I work on statistical theory, methods and computation, and applications in many disciplines, especially the social sciences. My research at The Alan Turing Institute will include:
• General approaches to scalability of statistical models and associated software (with Ioannis Kosmidis) • Scalable “scoring” in massive pair-comparison networks.
Applications of this are in commerce, bibliometrics, sport, etc.
• “Sports analytics” more generally (with Ioannis Kosmidis)
Professor Ruth King (EDINBURGH)
Ruth King is the Thomas Bayesí Chair of Statistics at the University of Edinburgh. She was awarded her PhD in 2001 from the University of Bristol.
She then held positions at the Universities of Cambridge (PDRA; 2001-3) and St Andrews (lecturer 2003-10; reader 2010-15) before taking up her appointment at the University of Edinburgh in 2015.
My main research interests involve the development of new statistical models and associated model-fitting techniques and their application to real data problems. Particular areas of interest include hidden Markov models/ state-space models; missing data; Bayesian inference; incorporating different forms of heterogeneity; capture-recapture; and applications particularly within ecology and epidemiology.
