Research profile

Algebraic geometry aims at classifying geometries that can be described in terms of polynomials. I am interested in special geometries with a rich algebraic, analytic and arithmetic structure. My main focus is on K3 surfaces and higher dimensional analogues which can be studied in terms of algebraic invariants like Hodge structures and derived categories. K3 surfaces and related moduli spaces are particularly interesting test cases for some of the central conjectures in algebraic geometry (eg. Tate, Hodge, Bloch-Beilinson).

Contribution to Research Areas

Research Area C
Homological mirror symmetry relates symplectic and algebraic geometry as an equivalence of categories (Fukaya category of Lagrangians resp. derived category of coherent sheaves). Fundamental aspects of both sides can thus be seen also from the mirror perspective which has led to new insight. In [1] we have proved the mirror analogue of a theorem of Donaldson on the action of the diffeomorphism group of a K3 surface.The conjectured braid group like description of the group of autoequivalences of the derived category of Calabi-Yau varieties of dimension two is an example and one of the main open problems in the area.
Research Area E
Spaces of stability conditions on abelian and triangulated categories form a new kind of moduli spaces with an intriguing wall and chamber structure reflecting the change of moduli spaces of stable objects. The main open questions in the are concern the global geometry of the space of stability conditions and the change of numerical and motivic invariants of the associated moduli spaces of stable objects. The case of the derived category of coherent sheaves on a K3 surface is of particular interest as moduli spaces of sheaves and complexes yield higher dimensional varieties with special geometries. A surprising relation to conjectures on the structure of Chow groups has been discovered in [2].
