Some of our research interests include:

- Moduli spaces of curves and abelian varieties, tautological classes, Siegel and Teichmüller modular forms, and their relation to the cohomology of moduli spaces, linear orbits of plane curves
- Arithmetic geometry and algebraic number theory, rational points of algebraic varieties, zeta functions and Galois representations associated to algebraic varieties
- Moduli spaces of sheaves, (virtual) enumerative geometry on 2-, 3-, and (Calabi-Yau) 4-folds, Donaldson-Thomas and related invariants, relations to combinatorics, modular forms, and theoretical physics
- Diophantine geometry, arithmetic applications of birational geometry, varieties over non-algebraically closed fields, Cox rings, Fano varieties, toric varieties, rationally connected varieties, rational points over global fields

Our members are part of the Dutch clusters Discrete, Interactive and Algorithmic Mathematics, Algebra and Number Theory (DIAMANT) and Geometry and Quantum Theory (GQT).
