Chun-Qing Li has been a professor of civil engineering since 2006 initially in UK and now at RMIT, Australia. He is a fellow of the Institution of Civil Engineers of UK (FICE) as well as the Institution of Engineers, Australia (FIEAust). He is also a chartered professional engineer of these two institutions. Professor Li has served on a number of professional bodies, including codes and standards committees, editorial boards, conference committees and so on. He was the Head of School of Civil, Environmental and Chemical Engineering in RMIT University from 2011 to 2016 during which period he changed the culture of the School, doubled the research outputs of the School and increased the ranking of Civil Engineering to within top 100 in the world. Professor Li’s core research expertise is time-dependent reliability theory and its application to whole life care of corrosion-prone infrastructure. His contribution to time-dependent reliability theory is that he derived a closed-form solution to first passage probability for non-stationary Gaussian stochastic processes in 1993 and more recently (2016) he derived a new solution to first passage probability for nonstationary and non-Gaussian process. Professor Li is one of the first researchers to advance research on corrosion from material perspective to mechanical and structural perspectives since 1998; one of the first to apply first passage probability method to service life prediction of deteriorating structures since 2004; one of the first to propose risk-cost optimisation for developing maintenance strategy for deteriorating structures since 2007; and one of the first to develop models for mixed modes fracture failures of buried pipes since 2013. Professor Li’s research in risk-based service life prediction of civil infrastructure was rated “international leading” (i.e., 4* - the highest rating) in UK’s 2008 Research Assessment Exercise. Professor Li has published over 300 papers and more than 170 papers are published in high quality international journals, e.g., ASCE journal of engineering mechanics, journal of structural engineering, ACI journals etc.. He has been awarded many research grants in total over $10 m since 2000 as lead or sole CI from both national research councils of UK and Australia where he has worked, e.g., UK’s Engineering and Physical Science Research Council (EPSRC) and Australian Research Council (ARC). Professor Li is ranked by Elsevier the “Top 2% scientists in the world” (the highest ranking) for both single-year impact in 2020 and for career-long impact based on more than 20 indicators. 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.
