Dr. Y. Richard Kim received his Bachelor’s degree from Seoul National University, Korea, and Master’s and PhD degrees from Texas A&M University, USA. Currently Dr. Kim is the Jimmy D. Clark Distinguished University Professor and Alumni Association Distinguished Graduate Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University and Changjiang Scholar in the School of Materials Science and Engineering at Chang’an University in China. Changjiang Scholar is the highest academic award issued to an individual in higher education by the Ministry of Education of the People’s Republic of China. He has over thirty years of experience in both the laboratory and field aspects of the performance evaluation of asphalt materials and pavements.

Professor Kim is a Fellow of the American Society of Civil Engineers and the Korean Academy of Science and Technology. He is also a board member of International Society for Asphalt Pavements (ISAP) and was the chair of the 2014 ISAP Conference on Asphalt Pavements. Dr. Kim has published over 300 papers in national and international technical journals and proceedings. He is the editor of the ASCE book entitled Modeling of Asphalt Concrete and the Editor-in-Chief for the Journal of Traffic and Transportation Engineering and International Journal of Highway Engineering. He has spoken at numerous national and international settings, including over 120 invited/keynote speeches.

Professor Kim teaches CE 332 Materials of Construction, CE 595A Bituminous Materials, CE 594C Nondestructive Evaluation of Civil Infrastructure, CE 755 Highway Pavement Design, CE 757 Pavement Management Systems, and CE 759 Inelastic Behavior of Civil Infrastructure. Professor Kim has advised 55 PhD students and 43 Masters students during his 30-year tenure at NC State University. His teaching and mentoring efforts were recognized by the Alumni Association Distinguished Graduate Professorship in 2012. Professor Kim has won numerous awards, including the Alexander Quarles Holladay Medal for Excellence (2019). The Holladay Medal is the highest award at NC State University to recognize members of the faculty whose careers have demonstrated outstanding achievement and sustained impact in research, teaching or extension and engagement. In 2016, Professor Kim became one of the eleven inaugural members of the Research Leadership Academy at NC State University. The Research Leadership Academy is the faculty-driven epicenter of research leadership and faculty mentoring enhancing NCSU’s research culture and is composed of the University’s most outstanding researchers and mentors from diverse fields.
