About me

👋🏼 I’m an HCI researcher at the intersection of technology, behavior, and health.

I am currently a Ph.D. candidate studying health informatics at the School of Information, University of Michigan. Co-advised by Dr. Mark W. Newman and Dr. Pedja Klasnja, I study how mobile health (mHealth) technologies can help people build a healthy and positive relationship with physical activity for long-term behavior change.

I am a human-computer interaction (HCI) researcher focused on advancing mobile health (mHealth) interventions that help individuals build healthy, long-term relationships with health behaviors, such as physical activity. By integrating insights from behavioral science with user-centered design, my work aims to understand the underlying causes and mechanisms of health behaviors and create interventions that are both effective and tailored to users' individual needs. My goal is to bridge the fields of HCI and health, designing solutions that empower individuals to make lasting, meaningful changes and improve their well-being in their everyday lives.
