I am an Assistant Professor at Harvard University with appointments in the Business School and the Department of Computer Science. I am also a Senior Staff Research Scientist (part-time) at Google. Previously, I earned my PhD in Computer Science from Stanford University and have held research and leadership roles at Microsoft Research, IBM Research, Adobe, and Fiddler AI.

My research interests lie within the broad area of the algorithmic foundations and societal implications of safe, trustworthy, and responsible AI. Specifically, I develop machine learning and optimization techniques, design evaluation frameworks, and conduct human-subject studies to improve the trustworthiness of predictive and generative models, including large language models (LLMs). My work spans themes such as safety, interpretability, fairness, privacy, reasoning, AI-assisted decision making, and human–AI collaboration.

My work addresses fundamental questions at the intersection of human and algorithmic decision-making, such as:

  1. How can we build interpretable and accurate models to assist and augment human decision-making?
  2. How do we identify and correct underlying biases in both human decisions and model predictions?
  3. How can we ensure that models and their interpretations are robust to adversarial and privacy attacks?
  4. How do we train and evaluate models in the presence of missing counterfactuals and unmeasured confounding?
  5. How do humans engage with AI models, and what factors shape effective human–AI collaboration?

These questions have far-reaching implications in high-stakes domains such as health care, policy, law, and business.

I lead the AI4LIFE research group at Harvard and I recently co-founded the Trustworthy ML Initiative (TrustML) to help lower entry barriers into trustworthy ML and bring together researchers and practitioners working in the field. My research is being generously supported by NSF, Sloan Foundation, Schmidt Sciences, Google, OpenAI, Amazon, JP Morgan, Adobe, Bayer, Harvard Data Science Initiative, and D^3 Insitute at Harvard. My work has been featured in various major media outlets including the New York Times, TIME magazine, Fortune, Forbes, MIT Technology Review, and Harvard Business Review.

Please check out my CV for more details about me and my research.

NOTE: I am looking for motivated graduate and undergraduate students and postdocs who are broadly interested in trustworthy machine learning and large pre-trained models. If you are excited about this line of research and would like to work with me, please read this before contacting me.
