My research concerns the processes and effects of social networks and communication technologies on promoting physical and mental health. Specifically, my research aims to understand and design online social networks that enhance exchanges of social support, the spread of credible health information, and social influence for health behavior change and improved psychological well-being. My recent work starts to explore using AI in online social networks for social support and combating health misinformation. My work has regularly appeared in journals such as Journal of Computer-Mediated Communication, Journal of Communication, Communication Research and Health Communication. 

I have a Communication and Computation for Well-Being Lab (CWell).
