After receiving a Ph.D. from National Tsing Hua University in 2004, served as a postdoctoral researcher at the University of California, Berkeley, before returning to Taiwan in 2008 to join the faculty at the Department of Materials Science, National Chiao Tung University. He is also jointly appointed as a researcher at Academia Sinica and a professor in the Department of Electrophysics at NCTU. His research expertise includes complex oxides, multiferroic materials, strongly correlated electronic systems, novel nanostructures, and heterostructure/interface analysis, application, and research. In the field of multiferroic materials, he ranks in the top ten worldwide, with his research on bismuth ferrite ranked among the top three. He has published over 205 papers with more than 10,000 citations (h-index=48, Web of Science) and over 12,000 citations (h-index=52, Google Scholar). In 2014, he was recognized by Thomson Reuters as a Highly Cited Researcher in Materials Science.
