My Research

My research is motivated by conceptual and mathematical problems of field theories. Symmetries and their fascinating occurrence throughout physics are the prevalent theme.

This translates into a broad spectrum of research interest:

  • infinite-dimensional symplectic manifolds with symmetries
  • moduli spaces of geometric structures
  • geometric quantization
  • representation theory of infinite-dimensional Lie groups
  • dynamics of infinite-dimensional Hamiltonian systems, especially in hydrodynamics and gauge theory
