I am a Senior Principal Researcher at Microsoft Research AI in the information and data sciences group.  My research interests span causal inference, machine learning, and AI’s implications for people and society.  I lead efforts on robust AI, including causal machine learning methods and security and AI concerns.

I am working to broaden the use of causal methods for decision-making across many application domains; and, in the broad area of AI’s implications for society, my projects include work at the intersection of security and machine learning.  I have a  strong interest in computational social science questions and social media analyses, especially that require causal understanding of phenomenon in health, mental health; issues of data bias; and understanding how new technologies affect our awareness of the world and enable new kinds of information discovery and retrieval.
