About

I graduated from Duke in 2014, where I studied mathematics.

In 2021, I received my PhD in mathematics from UCLA, where I was advised by Alexander Merkurjev. My work was mainly concerned with cohomological invariants of groups of multiplicative type. You can see my papers here.

Currently, I am a software engineer at Google.
