Qi Li received his Ph.D. degree in Materials Science at Wuhan University of Technology in 2013. From March of 2013 to November of 2016, he was a postdoctoral fellow at the Department of Materials Science and Engineering of the Pennsylvania State University. He started his appointment as an Associate Professor atthe Department of Electrical Engineering of Tsinghua University in December 2016. His research interest has been focusing on polymer-based nanocomposite materials with unique dielectric properties for electrical energy storage and conversion.His main scientific contributions include the development of state-of-the-art ferroelectric polymer nanocomposites for electrical energy storage and electrocaloric refrigeration applications, and the understanding of dielectric properties of polymeric materials under high electric fields and elevated temperatures. He has published over 50 SCI-indexed papers in journals such as Nature, PNAS, Nature Communications and Advanced Materials. He is the Guest Editor of Special Issue “Polymers for Film Capacitors” published by Materials, and an Editorial Board Member of IET Nanodielectrics. He was the recipient of the MRS Postdoctoral Award in 2016.
