Hossein Bahmyari, Ph.D., P.E., BC.GE, F.ASCE, a board-certified geotechnical engineer with over 20 years of experience leading innovative and high-risk civil infrastructure projects across the United States and internationally, has been named a fellow by the ASCE Board of Direction.
Bahmyari currently serves as a senior lead geotechnical engineer at Twining, Inc., where he provides strategic leadership and technical oversight on major projects involving bridges, tunnels, dams, highways, and high-rise structures. Known for his collaborative leadership style, strong project management capabilities, and forward-thinking solutions, he is widely recognized as both an effective team leader and an innovative design engineer.
Before joining Twining, Bahmyari was actively engaged in heavy civil construction and contributed to the design and execution of large-scale infrastructure projects. He also served as a technical advisor for tunnel and underground structures, offering expert guidance on complex geotechnical challenges in subsurface construction. In parallel, he spent nearly a decade as a university lecturer in his home country, where he taught civil and geotechnical engineering courses and mentored aspiring engineers.
Bahmyari is a Ph.D. Fellow and holds multiple degrees in civil engineering, including two master’s degrees – one in geotechnical and materials engineering. His technical expertise includes deep foundations, slope stability, ground improvement, dewatering, soil-structure interaction, and performance monitoring of geotechnical systems.
In addition to his project work, he actively conducts research and publishes technical papers in national and international journals. He has authored several publications, frequently presents at professional conferences, and is a recipient of multiple fellowships and awards recognizing both academic excellence and professional contributions. He has also been selected as an outstanding reviewer for several peer-reviewed journals.
Bahmyari serves on the editorial boards of several geotechnical journals, contributing to the advancement of the profession through scholarly review. He is also actively involved with the American Public Works Association (APWA), serving on the Education Committee for Southern California, and as a Session Chair for the Public Works Institute (PWI).
Within ASCE, he serves as a board member of the San Diego Section and as a session chair for ASCE Geo-Congress. He is a contributing member of the Geo-Institute’s Soil Improvement and Underground Engineering Committees. His leadership, technical service, and commitment to the next generation of engineers is demonstrated through his frequent lectures, technical presentations, and hands-on training sessions for practicing engineers and students.
