Hello! I am Orson — An HCI researcher

○  Postdoc @ MIT, 2023-present (Advisor: Marzyeh Ghassemi)

○  Ph.D. @ UW, 2018-23 (Advisors: Anind K. DeyJennifer Mankoff)

○  My research aims to leverage everyday data and build better human-centered methods, devices, and systems to sense, model, and influence our daily behavior toward enhanced health and well-being.

The figure shows the research contributions with the ground and two mountains. The ground has the phrase behavior modeling. One mountain has the phrase behavior intervention, and the other has the phrase intelligent intervention. The figure is surrounded by 17 publications corresponding to the three parts of the research contribution.

Research Overview


I am actively looking for self-motivated undergraduate and graduate students on various human-AI interaction / AI for health projects. Shoot me an email if you are interested!

Drawing from human-computer interaction, ubiquitous computing, AI/ML, and health, I develop deployable behavior modeling algorithms to monitor a range of health and well-being conditions. Leveraging these models, I further design and deploy intelligent intervention & interaction techniques that help achieve health and well-being goals.
