I am a doctoral candidate at the University of Washington's Programming Languages and Software Engineering group. My adviser is Zachary Tatlock. I am broadly interested in compilers and tools related to compilers, such as in producing tools to enable new kinds of programming, including tools built on proof assistants and SMT solvers to develop programs with proven correctness properties and compilers for domain-specific languages that better encode expert knowledge to achieve greater performance and expressiveness.

Presently I am part of SAMPL, which is an interdisciplinary research group holistically exploring problems spanning the machine learning stack. I am specifically working on projects related to Relay, whose purpose is to enable new abstractions and optimizations in machine-learning frameworks by providing an expressive intermediate representation and new compilation pipeline for TVM.

I have previously worked on the Bagpipe project, for verifying BGP configurations. An offshoot of the Bagpipe project is the SpaceSearch library, allowing for reasoning about the reduction of a problem to SMT in Coq and then extracting the proof of correctness to a solver-aided tool in Rosette.

I am not a member of the PLSE running club, Race Condition Running. I am, however, the only member of the Mutual Exclusion Walking Association. Its membership is very exclusive. In fact, no one can join because the waiting list is deadlocked.
