Sanjit Dandapanthula

ML researcher @ a new AI lab

About

I'm currently a member of technical staff at a new AI lab.

Previously, I was a PhD student at Carnegie Mellon University studying statistics and machine learning. During my time there, I also worked as a research intern at Abridge AI in New York City and Amazon Web Services in Santa Clara.

I studied mathematics and computer science at UCLA.

Research

I was extremely lucky to be advised by Aaditya Ramdas (now at Stanford) and Nicholas Boffi at CMU. My research interests are in generative modeling, deep learning theory, and optimal transport.

I am most fascinated by theoretical questions with immediate practical implications, such as:

Why do modern machine learning methods work so well?
Where do they fall short, and how can we design better ones?

Beyond research

In my spare time, I've been known to lift heavy things, watch TV shows, read books, and play board games with friends. I've recently enjoyed playing Gloomhaven: Jaws of the Lion and highly recommend the Mistborn and The Stormlight Archive series by Brandon Sanderson. I also play Indian classical music on the Bansuri flute.

In the past, I ran marathons, biked long distance, and hiked glacier mountains supporting Asha for Education (please donate here!), and volunteered for the Crisis Text Line as a Crisis Counselor (donate here!).
