AI/ML systems are powerful predictors, but they are not designed to answer counterfactual “what if” questions. My research combines flexible learning algorithms with causal inference methods to generate actionable evidence and develop tools for better decision-making.

I'm a PhD candidate in Epidemiology at Harvard, working with the Division of Pharmacoepidemiology at Brigham and Women's Hospital / Harvard Medical School, YLab, and CAUSALab.

Before graduate school, I spent five years as a research scientist at a healthcare analytics startup, building tools for real-world evidence generation.
