He received his PhD degree from Georgia Tech in 2005. His current research interests include understanding the coupling effect between piezoelectric polarization and semiconductor functionalities, and studying the growth mechanisms and developing assembly techniques of oxide nanostructures for mechanical and solar energy harvesting. He has published 82 papers in peer reviewed scientiﬁc journals, contributed 7 book chapters in his research ﬁeld, and holds 5 patents/provisional patents on oxide nanostructures and nanomaterial-enhanced energy harvesting. His publications have been cited over 6,000 times by peers and his current h-index is 36. He is the recipient of NSF CAREER Award, DARPA Young Faculty Award, 3M Non-Tenured Faculty Award, Ross Coffin Purdy Award, and Technology Review Young Innovators Under 35 Award.
