I am currently a research engineer at Google DeepMind, working at the intersection of self-supervised visual representation learning and natural language understanding. My research interests lie across machine learning theory and applications, computer security, and computer architecture.

In 2019, I was a visiting research student at ETH Zürich on a Fulbright Research Fellowship advised by Prof. Onur Mutlu. I completed my MEng with the Energy Efficient Circuits and Systems group at MIT MTL in 2018. Part of my research was also with the Spoken Languages and Systems Group at MIT CSAIL. During my MEng, I was advised by Professor Anantha Chandrakasan and Dr. Jim Glass.

In prior years, I had the worked on NVidia's Autonomous Driving Team to build new versions of PilotNet. In 2017, I worked with the Google Acoustic Modeling research team with Prof. Khe Chai Sim. In prior summers, I worked at Yahoo and Square.

I received my B.S. in Computer Science from MIT in 2016. Andover '13. HCSSiM '10. I love painting and building racecars.
