Dr. Wen Hui (Sophia) Cheng

Alumni - Research and National Labs



Wen-Hui (Sophia) Cheng received her B.S. and M.S. degrees from National Cheng Kung University, Taiwan, and pursed her Ph.D. from Caltech, all in Materials Science. During her Ph.D. research under the guidance of Prof. Harry Atwater, she focused on mesoscale design of photoelectrochemical fuel cells as part of the Joint Center of Artificial Photosynthesis (JCAP). She is currently a TomKat Postdoctoral Fellow mentored by Prof. Jen Dionne at Stanford University.
