About Me

I am a postdoctoral fellow in the Analysis Group at Delft University of Technology, working with Bas Janssens. Currently, I am also a Visiting Assistant Professor at the Shanghai Jiao Tong University.

In 2019, I completed my PhD at the University of Leipzig, Germany, and the Max Planck Institute for Mathematics in the Sciences, under the supervision of Gerd Rudolph.

My Research

I am interested in the mathematical aspects of classical and quantum field theories. Symmetries and their fascinating occurrence throughout physics are the prevalent theme of my research.

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
