PhD student, Computer Science · Johns Hopkins University

I’m a PhD student in the Social Computing group at Johns Hopkins , advised by Tiziano Piccardi. I study the gap between what people say they want from their social media feeds and what they actually engage with, and how to build feeds that take the first seriously.

More broadly I work on algorithmic auditing and computational social science. Before Hopkins, I did my MS at USC as part of the HUMANS Lab at ISI with Emilio Ferrara and Luca Luceri, and my BS in Computer Science & Engineering at Santa Clara University as a Clare Boothe Luce Scholar.
