Wen Hui (Sophia) Cheng

Graduate Student

Sophia Cheng began pursing her Ph.D. in Materials Science at Caltech in 2014 after finishing her M.S. and B.S. degrees at National Cheng Kung University, Taiwan. Her previous work includes the researches of thin film transistor (TFT), organic photovoltaics (OPV) and resistive memory device (RRAM) in Professor Jen-Sue Chen’s lab. As a member in the Atwater Group, she will focus on mesoscale design of photoelectrochemical fuel cells with JCAP.
