CV (as of 7/2022).

I am on github, twitter, google scholar, and semantic scholar.

I am currently a Research Scientist at AI2. Previously, I earned a PhD in Computer Science at Cornell University.

I work mostly on natural language processing, machine learning, and computer vision. If you're looking for me, I look something like this (facial hair subject to change):

  6. Helped with Cornell's annual Expand Your Horizons conference, where some friends and I taught a class on programming (2015, 2016)

Other Projects


I grew up in beautiful Portola Valley, California. I earned a B.A. from Carleton College in 2014, studying computer science and mathematics/statistics. During my time in Northfield, I played ice hockey, hosted a radio show, and was lucky enough to meet and work with a lot of great people. I even returned to Carleton briefly in 2019, this time, as a visiting faculty member! I'm a die hard San Jose Sharks fan, avid consumer (and very occasionally a producer) of electronic music, and, most of the time, a vegetarian (I am no longer a vegan!). During graduate school at Cornell, I was a member of Stewart Little Coop, a cooperative living community of 15 people, I played ice hockey in the Ithaca Hockey Association (and, during summer internships in CA, in the San Jose Adult Hockey League).
