I am currently a Medical Engineering postdoctoral researcher in the Gao Research Group at the California Institute of Technology. I received my B.S. in Electrical Engineering at University of Illinois at Urbana–Champaign and Ph.D. in Medical Engineering at California Institute of Technology. My current research interests include energy harvesting, wearable biosensors, and ingestible electronics.

Research Interests

I am deeply passionate about developing non-invasive biomedical sensor devices that continuously monitor physiochemical markers in-situ to indicate health and fitness, with the goal of optimizing individuals' lifestyles to suit their specific goals. With a bachelor's degree in Electrical Engineering and a graduate degree in Medical Engineering, I possess a unique capability to achieve development and system-level integration of all aspects of wearable and ingestible sensor devices, including energy harvester development, electronics design, sensor fabrication, system encapsulation, and system validation through human and animal studies.
