I am a postdoc at UCLA, where I work on computability theory and descriptive set theory.

Currently I’m mostly working on questions related to Martin’s conjecture, but I’m interested much more generally in logic and foundations of math. My goal is to work on problems that are both mathematically appealing and philosophically significant.

**Incompleteness and jump hierarchies**

*Comment:*Liang Yu has recently found a counterexample to Conjecture 5.36 (a.k.a. question 9.10)

**Berkeley Lean Seminar**

During Summer 2020, Thomas Browning, Rahul Dalal and I organized a seminar on the Lean proof assistant. The website for the seminar is here.**Galois theory in Lean**

Thomas Browning, Jordan Brown and I formalized various parts of Galois Theory in Lean. This culminated in a formalization of the Abel-Ruffini theorem on the unsolvability of the quintic (though I dropped out of this effort partway through to work on my thesis).**The Qual**

Once upon a time I took a qualifying exam and wrote up (most of) a transcript. I’m mostly proud of the picture I made to accompany it (and not so proud of the silly things I said during my qual).

**Current Teaching:** Math 285D, Introduction to Weihrauch Reducibility

**Past Teaching:** Here is a list of courses I’ve taught in the past. Also, here are websites I made for some of those classes:
