Research:

DFG Project "Higher Torsion Invariants".
In my Ph. D. thesis I investigated and calculated equivariant eta-invariants of homogeneous spaces. My advisor was C. Bär.
I work on analytic and differential-topological properties of eta-invariants, Ray-Singer torsion and related objects. In particular, I study their generalisations to families and group actions, partly in cooperation with J.-M. Bismut. Moreover, I try to calculate these invariants explicitly for as many classes of examples as possible.
At the moment, I compare the analytic torsion forms of Bismut and Lott with the higher Franz-Reidemeister torsion of Igusa and Klein. In this context, I also study "exotic" smooth structures for fibre bundles.
Together with U. Semmelmann, we worked on metrics with extremal scalar curvature.

Miscellaneous:

Workshop and miniconference Smooth Fibre Bundles and Higher Torsion September 1. - 7. 2003 at Göttingen (Programme of the miniconference: dvi, ps; report).

From september 1998 until september 1999 I've been a fellow of the Deutsche Forschungsgemeinschaft at the Equipe de Topologie et Dynamique of the Université de Paris-Sud in Orsay.

From February to July 2001 I've been a postdoc fellow of the MSRI at Berkeley in the special program on spectral invariants.
