I am an Associate Professor in the School of Information at the University of Michigan where I direct the Living Online Lab (LOL) and co-direct the Social Media Research Lab. I am also a member of the Michigan Interactive & Social Computing group. You can view a complete list of my publications with PDF links.

My research is in the areas of Social Computing, Social Media, and Human-Computer Interaction. Some current projects in my group are exploring ways of mitigating online harassment, ecommerce in peer-to-peer communities, and families' use of social media. My work has received Best Paper and Honorable Mention Awards at CHI and in 2017 I received the UMSI Faculty award for Diversity, Equity, and Inclusion. My research has been supported by the National Science Foundation, including an NSF CAREER award, and Facebook. Our work has been covered regularly in the New York Times, Washington Post, and on NPR as well as in Forbes, The Telegraph, CBS News, ABC News, The Atlantic, The Guardian, Seventeen Magazine, Vogue Australia, etc.

I received my PhD in Human-Centered Computing in the School of Interactive Computing at Georgia Tech where I was advised by Dr. Amy Bruckman. During my graduate work, I interned with HP Lab's Social Computing group and Microsoft Research's Social Media Group. I received my MS from the School of Information at UC Berkeley where I was advised by Dr. Peter Lyman. I received my BA from Dartmouth College in Computer Engineering.


I teach graduate and undergraduate Human-Computer Interaction courses at UMSI, including User Experience, Online Communities, and Interaction Design.

Prospective Students

Prospective PhD students must first be admitted to UMSI's PhD program before they can work with an individual advisor. Undergraduate and Masters students who have already been admitted to the University of Michigan and are interested in studying social media sites, online behavior, or designing or building new social computing systems are welcome to contact me. Include your interests, degree or major, and resume or CV. I typically will not invite a student to work in my research group unless I have had you in a class or you come recommended from a colleague, though I have made exceptions to this.
