Bashar Hariri (IntlAssoc)

Dr. Bashar Hariri is a PREP Research Associate with the Earthquake Engineering Group in the Engineering Laboratory at the National Institute of Standards and Technology (NIST). He is affiliated with The George Washington University through the PREP program and collaborates with the Department of Civil and Environmental Engineering at the University of California, Berkeley. His research centers on the seismic resilience and functional recovery of steel structures, with a focus on post-earthquake performance, advanced steel bracing systems, and experimentally validated approaches for resilient design.

Prior to his appointment at NIST, Dr. Hariri served as a Postdoctoral Research Fellow at the University of Toronto, where he conducted research on numerical hybrid simulation and full-scale experimental testing of innovative steel systems for high-seismic regions. His work has combined structural engineering, advanced computational modeling, and experimental investigation to improve the stability, resilience, and post-earthquake reparability of steel buildings.

Dr. Hariri earned his Ph.D. in Civil Engineering from Polytechnique Montréal. His doctoral and postdoctoral research has contributed to the advancement of seismic design strategies for steel buildings, including methods to mitigate P-delta effects, reduce residual deformations, and support the development of more resilient structural systems and design provisions.

Among his distinctions are the 2026 NIST PREP Award, the 2025 ASCE/SEI Future Leaders Scholarship, the 2024 AISC/SSRC Vinnakota Award, the 2024 ASCE/SEI Tier 1 Young Professionals Scholarship, the 2025–2026 John Charles Polanyi Prize nomination, the 2022 G.J. Jackson Fellowship Award, and competitive FRQNT doctoral and postdoctoral fellowships.
