About

I primarily work on building trustworthy machine learning models for time-to-event prediction (survival analysis) and for time series analysis. I often use nonparametric prediction models that work well under very few assumptions on the data. My main application area is in healthcare.

Survival analysis tutorial: Much of what I work on is survival analysis. I developed and taught a survival analysis tutorial at CHIL 2020 (co-taught with Jeremy Weiss) and at SIGMETRICS 2021. [tutorial webpage]

CoolCrop: I occasionally also work on machine learning for the developing world. I co-founded and now serve as an advisor for CoolCrop, an AgriTech startup based in India that works on providing farmers with cold storage units (such as a refrigerator shared by a village) and market forecasts. We're currently serving over 9000 farmers across 7 states in India at over 40 sites.

Pre-historic: I obtained my Ph.D. in Electrical Engineering and Computer Science at MIT. My thesis was on nonparametric machine learning methods. At MIT, I also worked on satellite image analysis to help bring electricity to rural India, and taught twice in Jerusalem for MEET, a program that brings together Israeli and Palestinian high school students to learn computer science and entrepreneurship. I completed my B.S. at UC Berkeley, majoring in Electrical Engineering and Computer Sciences, and Engineering Mathematics and Statistics.

Survival analysis symposium (Oct 2023): I co-organized a AAAI 2023 fall symposium on survival analysis/time-to-event prediction. [webpage]

Post doc Shu Hu will start in Fall 2023 as an assistant professor at IUPUI within the Purdue School of Engineering and Technology: many congrats to Shu!

Graduating PhD student Yue Zhao defended his PhD thesis and will start in Fall 2023 as an assistant professor at USC in Computer Science: many congrats to Yue!

PhD student Shahriar Noroozizadeh wins the Suresh Konda best first research paper award at CMU's Heinz College: many congrats to Shahriar!

NeurIPS 2023: I served as an area chair.

MEET Summer 2023: I returned to Jerusalem to teach computer science to Israeli and Palestinian high school students as part of MIT's Middle East Entrepreneurs of Tomorrow (MEET) program. I previously taught for this program in the summers of 2015 and 2016.

Regeneron International Science and Engineering Fair (ISEF) (May 7-13, 2022): This is a high school science and engineering fair that I was a finalist in back in 2006 (it was called Intel ISEF then). On May 11, 2022, I was on the Innovation, Entrepreneurship, and Impact panel (along with other ISEF alumni Ulyana Pena, Ashley Sarracino, Matthew Tamayo, and Mo Zerban), answering a variety of questions.

Conference on Health, Inference, and Learning (CHIL) (April 7-8, 2022): I was proceedings chair (with Gerardo Flores and Tom Pollard) [conference website]

NSF CAREER award (June 24, 2021): I received an NSF CAREER award for my proposed project on developing real-time nonparametric machine learning models for healthcare with guarantees
