About me

As of August 2023, I am a Research Scientist at Sony AI in the AI Ethics team. Excited to collaborate on topics related to ethics of generative AI!

Recently, I was a Postdoctoral Associate at MIT working with Phillip Isola and Marzyeh Ghassemi working on uncertainty estimation in generative models and efficiently updating LLMs.

Previously, I was a Research Scientist at Butterfly Network where I was part of the deep learning team led by Nathan Silberman. I obtained my Ph.D under Prof. Rama Chellappa, for which I was awarded the ECE Distinguished Dissertation Award.

I am interested in what makes a Machine Learning system trustworthy. I study this question from varied perspectives:

  • Interpretable Auditing: Quantifying when ML systems fail and reasoning why they fail.
  • Communicating ML decisions: Uncertainty estimation as a tool to effectively communicating ML predictions.
  • Value Alignment: Align machine learning model development with human values / expertise.
