Publications, awards, and scholarships
Welcome to the part where I try to convince you I’ve been doing something productive all this time. These publications are a collection of my research work on AI, sleep health, and wearable technologies — the result of many late nights, questionable debugging decisions, and an unhealthy amount of screen time.
