I am an assistant professor at University of California, Santa Barbara. I was a Zelevinsky Research Instructor at Northeastern University, working with Emanuele Macrì. I obtained my Ph.D. from University of Michigan in 2015, under the supervision of Herb Clemens and Karen Smith.

My research is partially supported by NSF grants DMS-2101789 and FRG-2052665.

Focused Research Group: Derived Categories, Moduli Spaces, and Classical Algebraic Geometry

Two upcoming events in 2022!

Workshop at Cornell University, April 29-May 1, 2022: Derived Categories and Moduli Spaces

Conference and minischool at the University of Michigan, July 30-August 5, 2022: Derived Categories, Moduli Spaces, and Hyperkähler Varieties

Several seminars that I help organizing:

Derived Seminar: Tuesday 8am-9am PT. This is an international seminar, centered loosely around derived categories in algebraic geometry.

UCSB Seminar on Geometry and Arithmetic: Thursday 4:30pm-6pm PT.

Learning Seminar on Algebraic Geometry: Friday 4:30pm-6pm PT.
