HCI & mHealth Research
PhD Candidate at the University of Michigan, School of Information, studying how mobile health technologies can help people build healthy, lasting behavior change.
Background
I am a Ph.D. candidate at the School of Information, University of Michigan, co-advised by Dr. Mark W. Newman and Dr. Pedja Klasnja. My research lives at the intersection of human-computer interaction (HCI) and behavioral medicine.
I study how mobile health (mHealth) technologies can support people in building sustainable relationships with health behaviors like physical activity — especially among middle-aged and older adults. By integrating insights from behavioral medicine and psychology with human-centered design, my work aims to understand and design for the underlying mechanisms that drive lasting change (i.e., intrinsic motivation, values and identity) that are both theory-driven and adaptive to users' dynamic and personal needs.
