Junqiao Wu


Professor Junqiao Wu received a B.S. from Fudan University and a M.S. from Peking University, China. He obtained a Ph.D. from the University of California, Berkeley for work on nitride semiconductors and highly mismatched semiconductor alloys. He did postdoctoral research in the Department of Chemistry and Chemical Biology at Harvard University on phase transitions in transition metal oxides. His honors include the Berkeley Fellowship, the 29th Ross N. Tucker Memorial Award, the U.C. Regents’ Junior Faculty Fellowship, the Berkeley Presidential Chair Fellowship, the NSF CAREER Award, and the DOE Early Career Award.

Dr. Wu's group explores novel properties and applications of correlated electron materials with reduced dimensions, phase transitions at the nanoscale, materials interfaces and composites, and photovoltaics, thermoelectrics and thermal properties of semiconductor alloys.
