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

Research Area C Homological mirror symmetry relates symplectic and algebraic geometry as<br />
an equivalence of categories (Fukaya category of Lagrangians resp. derived category of coherent<br />
sheaves). Fundamental aspects of both sides can thus be seen also from the mirror<br />
perspective which has led to new insight. In [HMS09] we have proved the mirror analogue of a<br />
theorem of Donaldson on the action of the diffeomorphism group of a K3 surface.The conjectured<br />
braid group like description of the group of autoequivalences of the derived category of<br />
Calabi-Yau varieties of dimension two is an example and one of the main open problems in the<br />
area.<br />
Former Research Area E Spaces of stability conditions on abelian and triangulated categories<br />
<strong>for</strong>m a new kind of moduli spaces with an intriguing wall and chamber structure reflecting the<br />
change of moduli spaces of stable objects. The main open questions in the are concern the<br />
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<br />
of coherent sheaves on a K3 surface is of particular interest as moduli spaces of sheaves and<br />
complexes yield higher dimensional varieties with special geometries. A surprising relation to<br />
conjectures on the structure of Chow groups has been discovered in [Huy10].<br />
