Bio

I am a second-year Ph.D. student at Stanford University, where I am advised by Professor Stephen Boyd. I conduct research in convex optimization and machine learning; I'm also passionate about building domain-specific languages for both. I am a principal developer of CVXPY, a domain-specific language for convex optimization that is used by many universities and companies. Previously, I was a full-time software engineer on the Google Brain team, where I worked on TensorFlow 2.0 and the core TensorFlow runtime.

If computer science is my first passion, then writing is my second: I served as a writer and investigative news editor for The Stanford Daily, and I blog at debugmind.com.

I graduated from Stanford in 2017 with a B.S. and M.S. in computer science and a minor in mathematics. I am currently supported by a Stanford Graduate Fellowship.

Industry

I always enjoy speaking with people working on real problems. If you're in industry and would like to chat about convex optimization, CVXPY, or TensorFlow, don't hesitate to reach out to me over email.

I have industry experience in designing and building software for machine learning (TensorFlow 2.0), motion planning and control for autonomous vehicles, and performance analysis of Google-scale software systems.

From 2017-2018, I worked on TensorFlow as an engineer on Google Brain team. Specifically, I developed a multi-stage programming model that lets users enjoy eager (imperative) execution while providing them the option to optimize blocks of TensorFlow operations via just-in-time compilation.

I honed my technical infrastructure skills over the course of four summer internships at Google, where I:

• conducted fleet-wide performance analyses of programs in shared servers and datacenters;

• analyzed Dapper traces for the distributed storage stack and uncovered major performance bugs;

• built a simulator for solid-state drives and investigated garbage reduction policies;

• wrote test suites and tools for the Linux production kernel.
