## Research

- Algebraic geometry (moduli spaces of curves and abelian varieties, arithmetic geometry, D-modules, Langlands program)
- Algebraic topology (calculus of functors, operads, rational homotopy theory, with applications to automorphisms of manifolds and spaces of embeddings)
- Combinatorics (graph theory, Ramsey theory, enumerative and algebraic combinatorics, polytopes)
- Commutative and homological algebra (homology theory of local rings, Gröbner bases, Koszul algebras, ideals generated by generic forms, computer algebra)
