# Dan M. Frangopol

Dan Mircea Frangopol is an American civil engineer and the inaugural holder of the Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture at Lehigh University, Bethlehem, Pennsylvania.
He became a member of the National Academy of Engineering in 2025 for contributions to life-cycle civil engineering and leadership in its global development and adoption.

## Education, career, and academic positions

Frangopol received his Diploma in Engineering from the Institute of Civil Engineering, Bucharest, Romania, in 1969 and his doctorate of Applied Sciences from the University of Liège, Belgium in 1976. His doctoral thesis, entitled Probabilistic Study of Structural Safety, was supervised by Charles E. Massonnet [de] and J. Ferry-Borges [pt].
After receiving his diploma in 1969, Frangopol held a position as assistant professor at the Institute of Civil Engineering in Bucharest until 1974 when he moved to Belgium to become a Research Structural Engineer (structural reliability, analysis and design of inelastic structures, structural optimization) in the Department of Mechanics of Materials and Structural Engineering, University of Liège.
In 1977 Frangopol returned to Romania as an associate professor at the Institute of Civil Engineering in Bucharest and moved to Belgium in 1979 working as a project engineer at A. Lipski Consulting Engineers in Brussels. In March 1983 he joined the faculty of the University of Colorado at Boulder as an associate professor in the Department of Civil, Environmental and Architectural Engineering. He was promoted to full professor in 1988 and become an emeritus professor in 2006.
In 2006 he moved to Lehigh University as Professor of Civil and Environmental Engineering and the inaugural holder of the Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture.
Since September 2009 he has been an Honorary Professor at Tongji University in Shanghai. Frangopol is an experienced researcher and consultant to industry and government agencies, both nationally and abroad. His work has been funded by NSF, FHWA, ONR, NASA, USACE, AFOSR, ARDEC, NCHRP, US DOT UTC, CDOT, FDOT, PennDOT, ASCE, NATO, and by numerous other agencies including Pennsylvania Infrastructure Technology Alliance, ArcelorMittal, Modjeski and Masters, Progeny Systems Corporation, Henry Luce Foundation, U.K. Highway Agency and the Dutch Ministry of Infrastructure and Environment.
He has authored or co-authored 5 books, 70 book chapters, over 490 articles in refereed journals (including 15 prize-winning papers from ASCE, IABSE, Elsevier, and EC$^3$ (European Council on Computing in Construction), and over 130 articles in ASCE journals), and more than 700 papers in conference proceedings. As of September 2024, his h-index = 103, i10-index = 482, and the total number of citations is over 39,000 (Google Scholar). Frangopol is the founding Editor-in-Chief of the peer-reviewed journal Structure and Infrastructure Engineering and the Founding Editor of the Book Series Structures and Infrastructures.
He is a pioneer in the fields of life-cycle civil and marine engineering and life-cycle cost optimization, and has been recognized as a leading educator and creator in these fields. Frangopol ranked as the 10th most-cited civil engineering author in the August 2019 Stanford University worldwide citation survey published in PLOS, and ranked No.1 (Lehigh University), No.45 (United States), and No.95 (World) on April 6, 2022, by Research.com on the list of top scientists in Engineering and Technology.
In 2012, Frangopol was described by ASCE as "a preeminent authority in bridge safety and maintenance management, structural systems reliability, and life-cycle engineering. His contributions have defined much of the practice around design specifications, management methods, and optimization approaches. From the maintenance of deteriorated structures and the development of system redundancy factors to assessing the performance of long-span structures, Dr. Frangopol's research has not only saved time and money, but very likely also saved lives." and in 2020, "Frangopol's groundbreaking research into infrastructure from a holistic perspective has earned him a reputation in the civil engineering community" as the "Father of Life-Cycle Analysis."
In 2023, ASCE established the "Dan M. Frangopol Medal for Life-Cycle Engineering of Civil Structures."
