I am an incoming PhD student in Nursing interested in digital health, healthcare AI, behavior change, and adaptive intervention design.
My current portfolio explores how walking behavior can be tracked, analyzed, translated into personalized micro-interventions, evaluated for safety and usability, and optimized through adaptive prompt timing.
Track → Analyze → Design → Evaluate → Optimize
A React-based digital health prototype for logging and visualizing walking behavior patterns by purpose and barriers.

I am interested in developing context-aware adaptive algorithms that help people initiate small, feasible health behaviors at the right moment.
My long-term goal is to design and evaluate digital health systems that translate behavioral data into safe, usable, and personalized interventions for chronic disease self-management.
