Bio and Research Interests

I am a Dean's Associate Professor in the School of Computing (Human-Centered Computing Division) at Clemson University. I received my Ph.D. in Information Science with a specialization in Computer-Mediated Communication (CMC) and Human-Computer Interaction (HCI) from the School of Informatics and Computing at Indiana University-Bloomington (IUB). Prior to joining Clemson, I was an Assistant Professor in the School of Information Technology at the University of Cincinnati (UC). At UC, I directed the game development and simulation tracks for the Master of Science and Bachelor of Science programs in Information Technology.

My research interests, broadly construed, focus on how interactive technologies, such as multiplayer online games, esports, live streaming, Artificial Intelligence (AI), and social virtual reality, shape interpersonal relationships and group behavior. My work brings a unique combination of profound theoretical foundation, nuanced empirical perspectives, especially in-depth qualitative insights, and participatory technology design and prototype to investigate mediated experience and social dynamics forged surrounding various technological and collaborative systems and artifacts, in order to design and develop more inclusive, supportive, and fulfilling user experiences with technology. My research is also uniquely driven by my focus on marginalized technology users due to their gender, race, age, and disability, including women, LGBTQ individuals, ethnic minorities, minors, and persons with disabilities. I have authored over 90 peer-reviewed publications and won 13 Best Paper or Best Paper Honorable Mention Awards (top 3%-5%). My work has been supported by the National Science Foundation (NSF), US Army, and the Air Force Office of Scientific Research.

At Clemson, I lead the Gaming and Mediated Experience Lab (CUGAME). If you are a prospective student who is interested in joining our lab, please read our CUGAME Lab Handbook. This document should help you understand who we are and whether our lab is a good match for your personality, interests, and research approaches.

By adopting a mixed-method approach including interviews, content analysis, surveys, and participatory technology design and prototype, our work has three interlinked research themes in HCI on social computing, games and play, and social VR:

(1) How novel digital social spaces such as gaming, virtual worlds, live streaming, and AI transform the ways in which people meet, interact, communicate, and collaborate online;

(2) IT innovation/making as a mechanism to broaden public participation in bottom-up technological innovation through online collaboration, such as independent game developers' and creative live streamers' engagement in shaping the trajectory of future technological advance; and

(3) Understanding and designing novel social Virtual Reality technologies for inclusion, diversity, and social good.
