I am a member of the Knowledge Discovery Laboratory, advised by David Jensen. I am broadly interested in using causal reasoning to develop robust systems for AI-driven decision-making. My research studies the identification of anomalous or malicious activity, development of methods for resilience and few-shot transfer of decision-making policies, and construction of empirical designs for evaluating behavior of complex (software) systems. My recent work is focused in the sequential decision-making setting and studies the problem of how machine-learning and AI systems can respond intelligently to unexpected inputs, anomalies, and other forms of novelty in the environment. I am particularly motivated by applications in fraud prevention, cyber security, and climate risk assessment.

- I was accepted as a 2018 Data Science for Social Good Fellow. For 3 months, I worked with a small team of fellows in partnership with AllianceChicago, a national network of 44 community health centers serving the least resourced members of their communities, on a project to support early diabetes screenings by identifying patients at risk of developing the disease in the next 3 years. Our code will be made publicly available. You can read an excerpt of my application in the UMass announcement. (August 2018)
