Very Short Bio:

I am currently a postdoc at the University of Hamburg.

Before that I was a postdoctoral fellow at the Max Planck Institute for Mathematics in Bonn.

Before that I was a PhD student in mathematics of Ingo Runkel at the University of Hamburg and was funded by the Research Training Group 1670 "Mathematics Inspired by String Theory and QFT".

Even before that I was a MSc student in mathematical physics at the University of Hamburg and before that a BSc student in physics at the Budapest University of Technology.

You can find my detailed CV here.

Research Interests:

• low dimensional quantum field theories
• in particular: topological, volume-dependent and conformal quantum field theories
• monoidal categories, (defect) bicategories
• moduli spaces of (r-spin) surfaces

You can find my research plan here.
