My research is supported by an NSF CAREER award on Understanding Inductive Biases in Modern Machine Learning, an NSF BIGDATA award on Privacy in Machine Learning, a DARPA award on  Robust Adversarial Learning, an NSF BIGDATA award on Stochastic Approximation for Subspace and Multiview Representation Learning, an NSF TRIPODS award on Foundations of Graph and Deep Learning, and an NSF CRCNS award on Computational Neuroscience. See here for more details.
Our work on Deep CCA was a finalist for the 2023 ICML Test-of-Time Award.


Bio: I am a member of the Mathematical Institute for Data Science (MINDS), the Center for Language and Speech Processing (CLSP) and the Institute for Data Intensive Engineering and Science (IDIES). Prior to joining Johns Hopkins, I was a Research Assistant Professor at the Toyota Technological Institute at Chicago (TTIC), a visiting researcher at Microsoft Research, Redmond and a research associate at the the University of Washington, Seattle. I received my Ph.D. from the University of Wisconsin-Madison.

During 2019 - 2020, I was a member of the Department of Mathematics at the Institute for Advanced Study. I was a visiting scientist at the Simons Institute for the Theory of Computing at UC Berkeley during summer 2019 program as part of the program on Foundations of Deep Learning, during Fall 2020 program as part of the program on Theory of Reinforcement Learning, and during Spring 2022 as part of the program on Learning and Games.
