I am a 4th year PhD student at Cornell Statistics, minoring in Computer Science. Broadly, I work on inference and interpretability of machine learning methods, in particular tree ensembles, and causal inference. I am advised by Giles Hooker and Martin Wells, and Thorsten Joachims is on my committee.
Previously, I studied at Berkeley and Columbia, and worked in startups and nonprofits in NYC. In 2014, I was a Data Science for Social Good fellow. I spent summer 2015 at Xerox Research in the machine learning group. I will be at Microsoft Research Redmond this summer. My work is supported by a Harmony Institute Research Fellowship and an Engaged Cornell grant.
