About Me

I am a PhD student studying human-centered AI at the University of Washington, advised by Ari Pollack, Wanda Pratt, and Orson “Xuhai” Xu. My research sits at the intersection of artificial intelligence (AI), human–computer interaction (HCI), and health informatics. Before my doctoral studies, I completed my master’s degree at the University of Michigan and then worked as a dietitian and research scientist across health organizations and tech startups such as Impossible Foods, Unita Health, and Dexcom.

My work combines human-centered design, mixed-methods user research, and AI/ML to study how intelligent systems can support human collaboration and decision-making in multi-stakeholder environments. I am especially motivated by work that measurably improves people’s lived experiences, or produces frameworks that help researchers and practitioners build more responsible, trustworthy AI. My research has appeared in high-impact venues such as ACM CHI conference, AMIA conference, and Nutrients journal.

I’m inspired by the late, great Kobe Bryant’s Mamba Mentality — his relentless commitment to inspiring those around him. If my work resonates with you, I’d love to connect and chat. Outside of research, I enjoy traveling and playing sports, mainly basketball and golf.
