ABOUT

Dr. Sanghamitra Dutta joined the University of Maryland, College Park in 2022. Her research interests broadly revolve around reliable and trustworthy machine learning. She is particularly interested in addressing the challenges concerning fairness, explainability, and law, by bringing in a novel foundational perspective deep-rooted in information theory, causality, and optimization. 

Prior to joining UMD, she was a senior research associate at JPMorgan Chase AI Research in the Explainable AI Centre of Excellence (XAI CoE). Her research on algorithmic fairness has been adopted as part of the fair lending model review at JPMorgan. 

Dr. Dutta received her Ph. D. from Carnegie Mellon University. Her thesis proposes a systematic quantification of the legally non-exempt disparity in machine learning models, bringing together causality, information theory, and law. She has received the 2019 K&L Gates Presidential Fellowship in Ethics and Computational Technologies for her research in this direction. Her research on quantifying accuracy-fairness tradeoffs using information theory (with IBM Research) was featured in New Scientist. Her thesis received the 2021 A G Milnes Outstanding Thesis Award.

In her prior work, she has also examined problems in reliable computing, proposing novel algorithmic solutions for large-scale distributed machine learning, using tools from coding theory (an emerging area called “coded computing”). Her results on coded computing address problems in algorithm-based-fault-tolerance that have been open for several decades and have received substantial attention from across disciplines. She has also pursued research internships at IBM Research and Dataminr.

Her research vision is to build the foundations of reliable artificial intelligence (AI), beginning from a fundamental understanding of the challenges in reliability and trust, and carrying them all the way to practical implementations, so that AI can truly bring about social good.

Her research interests include:

  • Fairness and Explainability
  • Information Theory
  • Optimization
  • Causality
  • Coded Computing
