I am a third-year Ph.D. student at the University of Washington's Programming Languages and Software Engineering group. My adviser is Zachary Tatlock. I am interested in program verification, both verification of existing programs and systems after the fact with proof assistants or solver-aided tools and developing tools and frameworks to make it easier to write programs with proven correctness properties.

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 the Relay project, 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.
