Hi! I’m a PhD student in Technology and Social Behavior, a joint program in computer science and communication studies, at Northwestern University. My advisor is Professor Jessica Hullman. My current research is on facilitating reasoning around the implementation of differentially private algorithms. Lately, I have also been thinking about how computer science researchers consider the downstream consequences of their work. I completed my master’s degree in information studies at the University of Amsterdam and my bachelor’s degree in statistics at UCLA.

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