Hi! I’m a PhD student in a dual program in computer science and communication at Northwestern University. My advisor is Professor Jessica Hullman. I’m interested in studying 1) how algorithms can be more effectively implemented and 2) their downstream consequences. Lately, I have been thinking about the social challenges arising around the U.S. Census Bureau’s adoption of differential privacy.

I also co-organize HCI+D’s PhD Book Club. We read books that help us think critically about technology and media.

During Spring 2022, I am a visiting PhD student at Columbia University working under the guidance of Professors Rachel Cummings, Elissa Redmiles, and Gabriel Kaptchuk on explaining differential privacy to end users.
