I’m an Assistant Professor in Computer Science & Engineering at the University of Minnesota. I work with other HCI faculty in the GroupLens lab. I build and critically evaluate human-centered machine learning (HCML) for high-risk health behaviors in online communities. HCML deliberately refocuses computational contributions and impacts on the needs of humans, communities, and stakeholders.
Using machine learning, I use digital trace data from millions of interactions on social media to identify high-risk behaviors in online communities. At the same time, I critically evaluate these predictive approaches and develop more ethical and compassionate research practices for ML and computer science.
My domain of interest for these questions is online communities and mental health, with special interests in dangerous or high-risk behaviors like severe eating disorder, opioid use disorder and recovery, and suicidal ideation and crisis.
I received my Ph.D. in Human Centered Computing at Georgia Tech with Munmun De Choudhury, and did a postdoc at Northwestern University, working with Darren Gergle.
My work has generously been supported by the National Science Foundation (NSF), Northwestern’s Center for Advancing Safety of Machine Intelligence (CASMI), Cisco Research, Google, and an Amazon Research Award.

10/9/23: So many updates. Great new papers from Leah Ajmani in FAccT on ethic practices in social media. Three papers at CSCW – mine on contextual gaps that manifest in ML models for mental health prediction, Leah Ajmani’s work on how Wikipedia page protection plays out in practice, and Mo Houtti’s interview study about workplace bias in VC. And congratulations to Mo, for the Best Paper Honorable Mention and Impact Recognition from CSCW.
And thanks to new funding source National Science Foundation and an extended collaboration with Cisco!
4/12/23: New paper for CHI 2023 with PhD student Ashlee Milton about TikTok & mental health, and CSCW 2023 preprint up about our work in video conference and bias with PhD student Mo Houtti. More pre-prints to come soon…
I was also on MPR (Minnesota NPR) to discuss social media and mental health. This was super fun to do!
Also welcome Dan to upgrade from MS to PhD!
Gracious thank you to new funding sources for my group: Amazon Research Awards and Northwestern CASMI!
9/29/22: It’s been a busy few months for me and my students. Hanlin Li published two papers (link to the first and second) about measuring and making more visible moderator labor in Reddit communities at ICWSM, one of which won a Best Paper Honorable Mention award. Yay! Ashlee also published her first workshop paper on the harms of content recommendations for mental health.
Also take a look at this new paper about practices for human-centered machine learning, which is forthcoming in the Communications of the ACM (CACM).
Two new PhD students have joined my group! Welcome Ava and Nuredin!
Also gracious thank you to new funding sources for my group: Cisco Research and Google!
