I'm a Human-Computer Interaction (HCI) researcher, currently an assistant professor appointed by the Department of Computer Science at City University of Hong Kong since 2022.

My research seeks to enhance individuals' everyday health and well-being through unlocking the potential of ubiquitous computing technologies. I build multimodal systems (e.g., speech interfaces, chatbots) to support self-tracking, design interventions to encourage health behaviors, and explore opportunities for utilizing personal data in healthcare contexts.

Short bio: I received my Ph.D. in Information Studies from University of Maryland in 2022 (advised by Dr. Eun Kyoung Choe), MS in Information Science and Technology from Penn State in 2017, and BEng in Computer Science from Southeast University in 2015, respectively. I was a UX researcher intern at Meta (People Engineering) in 2020 and Google (Android) in 2019.

Prospective students: Ph.D. admissions for Fall 2026 have closed. For future admission opportunities, please checkout the lab page.
