Ki Yong Kim received the Ph.D. degree in physics from the University of Maryland, College Park, MD, USA, in 2003. Then he worked at Los Alamos National Laboratory as a Director’s Postdoctoral Fellow. In 2008, he returned to the University of Maryland as an Assistant Professor and became a Full Professor in 2020 with the Department of Physics and the Institute for Research in Electronics and Applied Physics (IREAP). In 2021, he joined Gwangju Institute of Science and Technology (GIST) as Professor in the Department of Physics and Photon Science and Associate Director at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science (IBS), Korea. He is the author or co-author of more than 200 research papers and conference proceedings. His current research interests include intense laser-matter interaction; ultrafast optical, terahertz, and X-ray spectroscopy; laser-driven charged particle acceleration; and high-energy-density laboratory plasma physics. He is the recipient of the Marshall Rosenbluth Outstanding Doctoral Thesis Award presented by the American Physical Society (APS) in 2004; Postdoctoral Distinguished Performance Award by Los Alamos National Laboratory in 2007; both National Science Foundation (NSF) and Department of Energy (DOE) Early Career Awards.
