Younghan Bae
I am a Postdoc (supported by SNSF Postdoc.Mobility grant) at Utrecht University with Martijn Kool. Before this, I was a PhD student of Rahul Pandharipande at ETH Zürich. My CV can be found here.

Research Interests
I am interested in moduli spaces arising from algebraic geometry, including moduli spaces of curves, moduli spaces of sheaves, Picard stacks, abelian fibration, CalabiYau 4folds and intersection theory.
