My research interests are in Model Theory: a branch of Mathematical Logic which has connections and interactions with a broad range of other areas of Mathematics. In my work the interactions are mainly with algebra and combinatorics and several of my papers could equally well be described as work on infinite permutation groups: studying the automorphism groups of algebraic and combinatorial structures using a mixture of model-theoretic and algebraic methods, or using model-theoretic constructions to produce infinite permutation groups and combinatorial structures with prescribed properties. Within model theory my interests are currently in stability theory and its generalizations, and Hrushovski constructions. Below, you can find a list of my papers and preprints, some lecture notes and slides of talks I have given, and a few other research-related things.
The following list of papers is in approximate reverse chronological order. It also contains preprints, which can be downloaded in .pdf .dvi or .ps format. I have offprints of most of the older published papers (with the possible exception of ones published in books). If you would like one, then let me know by e-mail.
