About

I study the art and science of program verification and synthesis. I am a member of the madPL group, a world-class group of faculty and students at the forefront of programming languages, verification, and software engineering research.

I joined UW–Madison in 2015, after receiving my PhD at the University of Toronto, where I was advised by Marsha Chechik.

See my research agenda for an overview of my work. I'm always looking for ambitious PhD and undergrad students. Email me if you're interested.
