I am a research scientist at Facebook, working on safe and robust experimentation and causal inference. I am also interested in interpretability and algorithmic fairness. I received my PhD from Cornell Statistics, where I was advised by Giles Hooker and Martin Wells, with Thorsten Joachims and Rich Caruana on my committee. I am on the board of the Women in Machine Learning organization. I recently co-founded the Trustworthy ML Initiative.

Previously, I studied at Berkeley and Columbia, and worked in public policy in NYC, including the health department and public hospitals system. I was also a Data Science for Social Good fellow. I was fortunate to spend summers at Microsoft Research, working with Rich Caruana, Kori Inkpen, and Ece Kamar. Towards the end of my PhD studies, I was a visiting student and bioinformatics programmer at UCSF medical school.


I’m currently based in the SF Bay Area. You can reach me at ht395 AT cornell DOT edu.
