Dr. Dan M. Frangopol is the inaugural holder of the Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture at Lehigh University. Before joining Lehigh University in 2006, he was Professor of Civil Engineering at the University of Colorado at Boulder, where he is now Professor Emeritus. He is recognized as a leader in the field of life-cycle engineering of civil and marine structures. His main research interests are in the application of probabilistic concepts and methods to civil and marine engineering including structural reliability, probability-based design and optimization of buildings, bridges and naval ships, structural health monitoring, life-cycle performance maintenance, management and cost of structures and infrastructures under uncertainty, risk-based assessment and decision-making, infrastructure sustainability and resilience to disasters, and stochastic mechanics. Dr. Frangopol is the Founding President of the International Associations for Bridge Maintenance and Safety (IABMAS) and Life-Cycle Civil Engineering (IALCCE). He has authored/co-authored over 380 articles in archival journals including 9 award-winning papers. He is the Founding Editor of Structure and Infrastructure Engineering. Dr. Frangopol is the recipient of several medals, awards, and prizes, from ASCE, IABSE, IASSAR, and other professional organizations, such as the OPAL Award, the Newmark Medal, the Alfredo Ang Award, the T.Y. Lin Medal, the F. R. Khan Medal, and the Croes Medal (twice), to name a few. He holds 4 honorary doctorates and 14 honorary professorships from major universities. He is a foreign member of the Academia Europaea (Academy of Europe, London) and the Royal Academy of Belgium, an Honorary Member of the Romanian Academy, and a Distinguished Member of ASCE.Dr. Sunyong Kim is an Assistant Professor at the Department of Civil and Environmental Engineering at Wonkwang University, South Korea. He obtained his undergraduate degree in 1999 at Yonsei University, South Korea, and his Master of Science Degree in 2004 at Korea Advanced Institute of Science and Technology (KAIST). Under the supervision of Professor Dan. M. Frangopol, he received a Ph.D in Structural Engineering in 2011 from Lehigh University, USA. His research interests include life-cycle performance management of civil infrastructure based on reliability and optimization, structural health monitoring and damage detection, and probabilistic safety and risk assessment of structures under natural hazards. Sunyong Kim is the recipient of the 2014 ASCE J. James R. Croes Medal, the 2014 IABMAS Junior Prize, and the 2018 IALCCE Junior Award. He has authored/co-authored several articles in peer-reviewed journals and conference proceedings.
