Mengtao Sun obtained his Ph.D. in 2003 from the State Key Laboratory of Molecular Reaction Dynamics, Dalian Institute of Chemical Physics, Chinese Academy of Sciences (CAS). From 2003 to 2006, he worked as a postdoc at the Department of Chemical Physics, Lund University. Since 2006, as an Associate Professor, he has worked at the Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, CAS. In 2016, he became a Full Professor within the University of Science and Technology Beijing, China. His current research interests focus on plasmonic principle and applications on plasmon-enhanced molecular spectroscopy, and the plasmon-exciton coupling interaction for molecular spectroscopy and surface catalytic reaction. He has published more than 180 peer reviewed papers.
