I'm a postdoctoral fellow as part of the Harvard Data Science Initiative, where I work on developing machine learning methods for the social sciences. I received my PhD in computer science from Columbia University in 2023. Before that, I was an undergraduate at Harvard, where I lived in Leverett House from 2013-2016. As an undergraduate, I concentrated in computer science and statistics, and I was also a PAF and wrote for the Crimson. In my free time, I like to run, watch movies, and play Monopoly Deal. I'm looking forward to being back in Leverett House, and please don't hesitate to reach out about anything! - ## House Roles [Non-Resident Tutors](/house-roles/non-resident-tutors)
