About Me

I am currently a Lead AI/ML Engineer at Optum AI (UnitedHealth Group), where I feel incredibly lucky and honored to collaborate with many talented people on meaningful and impactful problems that help people live healthier lives and help make the health system work better for everyone (See our Mission & Values) ! Prior to that, I worked as an Applied Scientist at Amazon, focusing on search, ranking, pricing, and large language model applications.

Before joining industry, I completed my Ph.D. in Computer Science at Purdue University Purdue University, where my research spanned optimization, machine learning, causal inference, and natural language processing. I also served as a postdoctoral researcher there. I received my B.S in the Computer Science Department at National Tsing Hua University and worked as a Research Assistant at Academia Sinica before moving to Purdue.
