Research mathematician, Oxford.
I am a research mathematician interested in aspects of algebra, analysis, combinatorics, geometry and number theory, with particular emphasis on using tools from the former to address problems in the latter. I completed my PhD in additive combinatorics under the direction of W. T. Gowers in 2007, during which time I benefited considerably from conversations and collaboration with B. J. Green.
Currently I am a senior research fellow in the Mathematical Institute at the University of Oxford, a university research fellow with the Royal Society, and a tutorial fellow at St. Hugh's College, Oxford. Between 2006 and 2011 I was a research fellow at Christ's College, Cambridge working in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge. For the academic year 2007–2008 I was a member of the School of Mathematics at the Institute for Advanced Study, Princeton; for the fall semester 2008–2009 I was a member of the Mathematical Sciences Research Institute, Berkeley; and for the spring semester 2008–2009 I was a member of the Institut Mittag-Leffler, Stockholm.
Anyone interested in my work is welcome to contact me either through my departmental page, my Mendeley profile or by e-mail at tom.sanders@maths.ox.ac.uk.
The following list may also be found on arXiv in the order in which the papers were updated starting with the most recent update. Partial versions of the list appear on MathSciNet, Zentralblatt MATH, and my Mendeley profile. Note that some of the MathSciNet and Zentralblatt links require subscriptions to access in their entirety.
ArXiv versions of papers are at least as up-to-date as those linked to from DOIs, although journal formatting is not included.
