I am a Senior Research Fellow of the Mathematical Institute at the University of Oxford, a University Research Fellow with the Royal Society, and a Tutorial Fellow of St Hugh's College, Oxford. My research interests lie in aspects of algebra, analysis, combinatorics, geometry and number theory, with particular emphasis on using tools from the former to address problems from the latter.

Anyone looking to contact me with regard to research can do so at tom.sanders@maths.ox.ac.uk or use the more traditional contact details available on my departmental page. Similarly, for college matters there is tom.sanders@st-hughs.ox.ac.uk and my college page.

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 and Zentralblatt MATH. 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.
