I am an Assistant Professor at Carnegie Mellon University with joint appointments in the Machine Learning Department and the Institute for Software, Systems, and Society. I am also affiliated with CyLab and Block Center at CMU, and I co-lead the university-wide Responsible AI Initiative.

I am broadly interested in the Societal Aspects of Artificial Intelligence and Machine Learning. For more information, please take a look at my bio, CV (last updated Aug 2022), Google Scholar profile, and the Research section of this page.

I currently advise the following doctoral students: Michael Feffer (co-advised with Zack Lipton), Keegan Harris (co-advised with Steven Wu).

If you are interested in working with me, I currently have graduate internships and a postdoctoral position available. Prospective doctoral students should directly apply to the appropriate graduate program at CMU (e.g., Machine Learning, Societal Computing, or Public Policy).

My work has been generously supported by the NSF Program on Fairness in AI in Collaboration with Amazon, PwC, CyLab, Meta, and J. P. Morgan.
