I am an Assistant Professor in the College of Information (INFO) and the Institute for Advanced Computer Studies (UMIACS) at the University of Maryland, College Park. I am a member of the CLIP Lab.

My research develops end-to-end data science solutions that combine machine learning, causal inference, and field experiments. My current research focuses on using AI to identify, measure, and promote effective teaching practices in K-12 education. This research builds on my broader work studying how social identity and non-verbal cues promote and facilitate collaboration and participation in virtual workspaces and online platforms.

I received my Ph.D. from the School of Information at University of Michigan. I was fortunate to be advised by Prof. Qiaozhu Mei and be a member of the Foreseer Group. Here is my CV.

Prospective Students:

We have funding available for multiple PhD students. I am able to mentor doctoral students through both the College of Information Studies and the Department of Computer Science. If you are interested in working with me, please apply to either program and mention my name in your statement so that your application can be routed for my review. While I welcome inquiries, I find research statements and recommendation letters valuable in evaluating fit, so I prefer to review complete application packages. Feel free to email me after submitting your application.

I'm also happy to work with masters and undergraduate students at UMD. If you are interested in research opportunities, please send me an email with your CV and transcript. While I try to respond to all messages, I may not be able to reply to every inquiry due to the volume of emails.
