I am a postdoctoral researcher at Universität zu Köln (supported by CRC/TRR 191), in the research group of Hansjörg Geiges. I finished my PhD at Universität Leipzig/MPI MIS in 2017 under the supervision of Matthias Schwarz. I am mainly interested in topological and dynamical aspects of contact and symplectic manifolds.
