Currently, I am a Postdoc/associate member at the Hausdorff Center for Mathematics, Bonn. Starting in September 2022, I will be a postdoc at the University of Bonn. My postdoctoral mentor is Prof. Daniel Huybrechts. I graduated from Northwestern University with a PhD thesis written under the supervision of Prof. Mihnea Popa.

### Research Interest

Birational geometry, Hyperkähler geometry, generic vanishing theory, Hodge modules and Hodge theory. Here is my CV.### Publications and Preprints
