I am an engineer and computer scientist living in San Francisco. I'm broadly interested in many topics including machine learning, computer vision, system design, optimization methods, programming languages, compilers, and high-performance computing. I guess you can say I've had a hard time staying faithful to one technical area.

I was a researcher at Microsoft Research Silicon Valley from 2007 to 2014. Prior to that I was at Microsoft Research Cambridge and a research fellow at Trinity Hall in the University of Cambridge . From 2015 to 2021 I worked at Apple .
