Education & Employment Member 2023 - Present

My work draws broadly from higher category theory, chromatic and equivariant homotopy theory, and algebraic K-theory to solve problems in algebraic topology and seek out connections to other fields of math.

In Spring 2023, I am teaching Math UN1102, Calculus II, at Columbia University. The course webpage can be found on Courseworks. Previous teaching: In Spring 2022, I taught Math UN2010, Linear Algebra, at Columbia University.

The seminar will meet on Fridays 11:00am – noon in person in Mathematics 507 (**NOTE THE NEW ROOM**). Please contact Inbar Klang or Allen Yuan with any inquiries regarding the seminar. April 1: Inna Zakharevich (Cornell) Detecting non-permutative elements of K_1(Var) using point counting
