The central theme of my research is understanding why deep learning works so well, and what are some theoretical explanations behind its successes and failures. With this aim, I have firstly worked on understanding common training time tricks like Dropout and Batch-Normalization. Secondly, I have worked on understanding and improving adversarial attacks and defenses for neural networks, by formulating a game-theoretic framework to study them, as well as exploring principled ways to defend against adversarial examples for the data domains of Graphs and Videos.
I received the JHU MINDS Data Science Fellowship in 2020 and 2019. My research is also supported by NSF and DARPA grants.
