Weiyang (Fiona) Li

William P. Harris Career Development Associate Professor of Engineering

Seminar: Enabling Next-Generation High-Performing Sodium Batteries


Dr. Weiyang (Fiona) Li graduated with BS and MS degrees in chemistry from Nankai University (Tianjin, P.R. China), and a PhD in biomedical engineering from Washington University in St. Louis (with Prof. Younan Xia). She then worked as a postdoctoral associate with Prof. Yi Cui in the Department of Materials Science & Engineering at Stanford University from 2011 to 2015. Her research primarily focuses on the development of functional materials with finely tailored composition and architecture to tackle critical problems in diverse energy-related applications, especially in cost-effective and high-energy battery systems. In her spare time, she enjoys painting, hiking, traveling and watching basketball games.
