Welcome! I am a postdoctoral fellow in computer science at Harvard University, as part of the Center for Research on Computation and Society (CRCS) and OpenDP. I am hosted by Professor Salil Vadhan. My work aims to integrate privacy into data-driven tasks using techniques from human-computer interaction and visualization. Much of my work aims to enable privacy-preserving data science by developing tools to make differential privacy usable. More recently, I have become interested in enabling privacy-preserving human-AI interactions, specifically in the context of conversational AI. I am a 2024 MIT EECS Rising Star and Data Science Rising Star.

I received a joint PhD in computer science and communication from Northwestern University, where I was part of the Midwest Uncertainty Collective and advised by Professor Jessica Hullman. During my PhD, I was a visiting researcher at Columbia University, a visiting graduate student at Simons Institute, UC Berkeley, and a research intern at Microsoft Research in FATE and SMC.
