Lóránt Szegedy
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 and conformal field theories
- higher categories, defect bicategories of 2d QFTs
- moduli spaces of (r-spin) surfaces, moduli spaces of flat connections on surfaces
- fully extended topological field theories
You can find my research statement here.
