I am a PhD student in the Paul G. Allen School of Computer Science & Engineering at the University of Washington, where I work with the Programming Languages and Software Engineering (PLSE) group. Click here for more info. I do research in AI (abstract interpretation). I am currently an intern with the AWS Privacy & Security Automation Group.

Software tooling and programmer productivity are my main interests. I find it most rewarding to work on problems that programmers actually face in practice; solutions to which will prevent incorrect code from ever being written and deployed in the first place. I've gotten my feet wet in industry, ranging from small startups with 4 backend developers, to behemoths like @twitter.

Before all that, I earned my Master's degree in Computer Science at @ubc, where my thesis investigated how developers investigate data-flow reachability questions, working on user interfaces and IDEs was fun!
