About

I am an Assistant Professor at Georgia Institute of Technology.

In Fall 2024, I am teaching Math 4022 (Introduction to Graph Theory).

My research interests are extremal, probabilistic, and algebraic combinatorics, especially Ramsey theory, graph coloring, additive combinatorics, discrete geometry, and coding theory, and their applications to computer science.

Previously, I was an NSF postdoctoral research fellow at Princeton University working with Noga Alon. Before that, I received my PhD in mathematics from Stanford University in 2021, where my advisor was Jacob Fox.

You can find my CV here. I blog about life, research, and rationality at my personal blog; most of my better posts can also be found cross-posted on LessWrong.

If you are a student interested in reading or working with me, please reach out after taking a look at problems and my blog to get a sense of my research interests and philosophy.
