Bio

I am a first-year Ph.D. student at Stanford University, where I am advised by Professor Stephen Boyd; I am supported by a Stanford Graduate Fellowship. I conduct research in optimization and machine learning, along with their applications. I am one of the primary designers of CVXPY 1.0, 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.

I graduated from Stanford in 2017 with a B.S. and M.S. in computer science and a minor in mathematics. I focused my studies in computer systems, artificial intelligence, and theory. During my undergraduate and Master's career, I published research in convex optimization and applied machine learning with Professor Boyd and Dr. Andreas Paepcke. Throughout my time at Stanford, I have been fortunate to have Professor Mehran Sahami as a mentor.

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

Industry

I am currently a software engineering intern at Aurora, where I'm working to make motion planning for autonomous vehicles fast and reliable.

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:

• applied data science to conduct 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.
