I am the Director of US R&D at Certora and affiliate assistant professor at University of Washington, Seattle. Before this, I graduated with a PhD from the PLSE group at the University of Washington, Seattle where I worked with my incredible advisors, Zachary Tatlock and Dan Grossman.
I am interested in building tools
for scaling automated formal verification to real-world programs;
we are focusing on DeFi applications specifically.
As part of this vision,
we are working on new verification tools for languages like WASM and
techniques to help users write formal specifications more easily using
mutation testing.
I also work on equality saturation
and its applications in synthesis, verification, and optimization.
Our work on Carpentry Compiler and
Szalinski are some of the first
tools that use equality saturation as a technique for optimizing unconventional compilers and
for program synthesis.
We also built Ruler,
a very cool tool that uses equality saturation to
synthesize rewrite rules for equality saturation!
I have developed
programming languages, correct compilers, and
synthesis tools for computational geometry
and fabrication.
I still work on these topics whenever I can.
We built LambdaCAD,
a functional programming language for
3D modeling that supports 3D primitives, affine operations, and
boolean operators to compose designs.
The LambdaCAD compiler generates a triangle mesh from a LambdaCAD program.
Using our compiler infrastructure and 3D geometry kernel,
we built a decompiler, called Reincarnate,
that uses evaluation context to synthesize LambdaCAD programs
back from meshes.
Check out my thesis for more details
on the correctness of our compiler for a subset of
LambdaCAD and for open problems in computational fabrication that can be
tackled with PL techniques!
Check out our tools, papers, talks, and more.
