I am a research scientist at Facebook. 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. During the later years of my PhD studies, I was based in the SF Bay Area where I was a visiting student and bioinformatics programmer at UCSF.
Broadly, I work on interpretability of machine learning methods. I'm also interested in algorithmic fairness and causal inference. I particularly enjoy working on methods useful for healthcare and public policy.
Previously, I studied at Berkeley and Columbia, and worked in public policy in NYC, including the health department and public hospitals system. In 2014, I was a Data Science for Social Good fellow. I spent two summers at Microsoft Research, working with Rich Caruana, Kori Inkpen, and Ece Kamar. I'm on the board of the Women in Machine Learning organization.
I’m currently based in the SF Bay Area. You can reach me at ht395 AT cornell DOT edu.
- 10/19: I gave a talk at Data & Society’s Meeting on Fair ML in Health about risk scoring models in healthcare.
- 7/19: I had a blast helping out with UCSF’s AI4ALL program! I presented on dataset bias and helped mentor a project team using electronic medical records to predict opioid overdose and other conditions.
- 4/19: I will be giving a talk at Columbia’s Data Science Institute in the Data for Good seminar series.
- 3/19: I’m excited to help teach the new ML for biomedicine course at UCSF. This is perhaps the first official ML course at UCSF and I’m looking forward to teaching again!
- 12/18: I’m co-organizing a workshop at ICLR 2019 on Debugging ML models. Submit your paper or demo!
- 6/18: Honored to receive a Microsoft Research Dissertation Grant
- 6/17: Grateful to receive the American Statistical Association Wray Jackson Smith Award
- 3/17: My project evaluating the impact of later school start times in NYC public schools has received an Engaged Cornell grant. You can read more about it here and here
