Principal Investigator

Prof. Ping Liu

Dr. Ping Liu is a Professor of Nanoengineering and the Director of the Sustainable Power and Energy Center at UCSD. Prior to joining the Jacobs School faculty, Professor Liu was a Program Director at the Advanced Research Projects Agency – Energy (ARPA-E), where he initiated and managed research programs in energy storage for electric vehicles and thermal management technologies to improve building energy efficiency. He was the manager of the Energy Technology Department at HRL Laboratories (an industrial lab jointly owned by GM and Boeing) and was a research staff member with the National Renewable Energy Laboratory. Professor Liu received his Ph.D. in Chemistry from Fudan University in China. He was a Distinguished Inventor in multiple years at HRL and won an R&D 100 award in 2009 for a battery technology developed at NREL.
