About Me

Social media has some very real toxicity challenges, like harassment and cyberbullying, that diminish its utility for collective and democratic efforts, and I study human-AI content moderation to address those challenges (NSF Grant, Belfer Fellowship, Mozilla Grant, Nayar Prize). I also study data curation, especially how we evaluate (a) the impacts of data reuse and (b) investments in curating and disseminating research data. My work has been funded by the National Science Foundation, the Institute for Museum and Library Services, the Nayar Prize, Mozilla, the Anti-Defamation League, Amazon, and DiscoverText.

I have a few titles at the University of Michigan:

Work with Me

Thank you for your interest! I’m not recruiting students or postdocs in the next 6 months (at least).

PhD Students

I’m not sure whether I’m recruiting PhD students for fall 2023. Check out some of my research, and contact me if you’re interested.

PhD students will be admitted through the School of Information; applications are due December 1. Here are some of the questions I’m working on:

I’m especially interested in students who are curious about the impact of social media on democracy and civic engagement and how we can use computation and automation to make conversations and participation (in politics, in science, in society) more just and accessible. You should have stats and computational expertise or be willing to gain some quickly. You should also have expertise or a strong interest in political science, critical race and feminism studies, and/or communication.
