Professor Ross B. Corotis, NAE, is the Denver Business Challenge Professor of Engineering at the University of Colorado in Boulder. He studies probabilistic concepts, particularly emphasizing the coordinated roles of engineering and social science with respect to framing and communicating long-term hazard risks and resiliency for the built environment. His primary research applications have been in loads and seismic safety, but he has also served on several flood study committees. With all three degrees from MIT, he was on the faculty at Northwestern University, established the Department of Civil Engineering at The Johns Hopkins University, and was Dean of Engineering at CU. He has won numerous awards, chaired committees on structural safety for ASCE and ACI and the Executive Committee of the International Association for Structural Safety and Reliability, and was Editor of the journals Structural Safety and ASCE Journal of Engineering Mechanics. For The National Academies he served on the Building Research Board, the steering committee of the Disasters Roundtable, was founding chair of the Committee on NIST Technical Programs, is currently on the Board on Infrastructure and the Constructed Environment, and chairs the Laboratory Assessment Board. He was Past Chair of the Civil Engineering Section of the National Academy of Engineering. He is He is a registered professional engineer and structural engineer, Distinguished Member of ASCE and 2019 recipient of their Lifetime Achievement Award in Education, and author of more than 250 publications. In 2007-2008 he served as science advisor at the Department of State in Washington, DC.
