Gilbert Hegemier

Gilbert Arthur Hegemier is an American engineer and academic known for his work in structural and aerospace engineering, as well as applied physics. He is a Distinguished Professor Emeritus at the Jacobs School of Engineering at the University of California, San Diego (UCSD), and is recognized as one of the founding faculty members of the institution. Hegemier's research has focused on enhancing public safety through the development of retrofitting techniques for structures in earthquake-prone areas, as well as on protective technologies against blast and ballistic threats. His contributions have been acknowledged by his involvement with professional organizations such as the American Institute of Aeronautics and Astronautics, the Earthquake Engineering Research Institute, and the American Society of Mechanical Engineers, where he has been a fellow since 1997.

Biography

Hegemier earned his M.S. and Ph.D. in Solid Mechanics and Structures from the California Institute of Technology. Early in his career, he worked as a mechanical engineer at several organizations, including TRW Systems Space Technology Lab, the National Engineering Science Company, and the Naval Ordnance Laboratory. His professional focus shifted toward earthquake safety following the 1971 San Fernando Valley and 1972 Nicaragua earthquakes. At UCSD, Hegemier led a team that developed and tested full-scale bridge column retrofit systems. These systems were notably effective during the 1994 Los Angeles earthquake, helping to minimize damage to retrofitted bridges. His research also includes work on using lightweight fiber-reinforced composites for infrastructure repair and developing methods for blast mitigation to protect critical structures.
