Background
- Assistant Professor in the Department of Statistics at University of California, Irvine
- Affiliated with UCI's Alzheimer's Disease Research Center (ADRC) and Institute for Future Health (IFH)
- Research focuses on developing data science tools for optimizing adaptive digital interventions
- Key research areas: causal inference in longitudinal settings with time-varying treatments, experimental design for micro-randomized trials (MRTs) in mHealth, and policy learning from offline/online data
- Collaborates with scientists across domains including physical activity, substance abuse, smoking cessation, weight management, drinking behavior, and anger management
- Additional research interests: semiparametric efficiency theory, clinical trial design and analysis, Alzheimer’s disease and related dementia
