*"I learned very early the difference between knowing the name of something and knowing something."-Richard P. Feynman-*

I'm mainly interested in algebraic geometry and representation theory.

Besides mathematics, I love boxing and playing the guitar.

And my advisor is Andrei Okounkov.

This semester, Noah Arbesfeld, Henry Liu, Petr Pushkar and I are organizing a seminar on Enumerative Geometry. If you're also interested in counting, please join us.

Location: Mathematics Building 622.

Time: Wednesday 2:30 pm-4:00 pm.

Website: Student Enumerative Geometry Seminar.

Reference: Lectures on K-theoretic computations in enumerative geometry.
