About me

I'm a PhD student in Mathematics at ETH Zürich in the group of Rahul Pandharipande. Previously, I was an undergraduate student at the University of Bonn in the group of Daniel Huybrechts. My research focuses on algebraic geometry with emphasize on enumerative geometry and various aspects of K3 surfaces and Calabi–Yau threefolds.


Starting in fall 2022, I am a Taussky–Todd Instructor in Mathematics at Caltech.


Notes and slides from recent talks:

Symmetry and enumerative geometry of Calabi–Yau spaces

Symmetry for stable pair invariants via derived equivalences -- the STU model

Curves on K3 surfaces -- what to do with multiple covers?
