I study human experiences in technical systems

About Me
The goal of my research is to support online environments in ways that enable freedom to flourish and from oppression. My work has covered key areas such as motivations, informal learning, privacy and ethics, and online governance. To this end I use a variety of methods, from qualitative ethnography and in-depth interviews, to quantitative surveys and social network analysis.
Currently, I'm the Research Director at the Citizens and Technology (CAT) Lab, founded by Dr. J. Nathan Matias.
Prior to that, I graduated from the University of British Columbia in 2018, where I was advised by Drs. Caroline Haythornthwaite and Luanne Freund and worked as a postdoctoral scholar at the University of Maryland on the NSF funded PERVADE (Pervasive Data Ethics for Computational Research project with Drs. Katie Shilton and Jessica Vitak. I also lead the NSF-funded project, Learning Code(s): Community-Centered Design of Automated Content Moderation with along with PIs, Drs. Katie Shilton, Hal Daumé III, and Michelle Mazurek until the grant was cancelled in 2025.
My hobbies include rewatching Star Trek over and over again (DS9 is the best Trek); cuddling with my cat, Rambo and my dog, Dax; cooking and baking; hiking; and going on day trips. Next time you're in the DC area, I promise that a jaunt to Dinosaur Land won't disappoint!
