Lelio H. Mejia

PhD, PE, GE – Biographical Sketch

Dr. Mejia is a registered civil engineer with over 35 years of professional experience. He is a Senior Principal at Geosyntec Consultants in Oakland, California, where he leads the firm’s west region dams and levees practice. His main fields of expertise include dam engineering, soil liquefaction, seismic hazard and earthquake ground motions, soil-structure interaction, and soil improvement.

Dr. Mejia has directed the investigations and seismic stability studies of over 25 large earth dams and has been involved in the design and construction of over 15 major dam projects. In addition, he has managed the design and overseen the construction of several dam projects, including projects over $300 million in construction costs.

Dr. Mejia has conducted research on the use of three-dimensional and nonlinear models for the dynamic response analysis of dams and on liquefaction failure during earthquakes. He developed earthquake loading criteria that served as a basis for those that were recently adopted by the International Commission on Large Dams (ICOLD) for the seismic evaluation and design of dams worldwide.

Dr. Mejia is currently Chair of the Earthquakes Committee of the United States Society of Dams, and until recently was a member of the National Research Council (NRC) Committee on State of the Art and Practice in Earthquake Induced Soil Liquefaction Assessment. He was a Secretarial Appointee to the Advisory Committee on Structural Safety of the Department of Veterans Affairs Facilities and Chair of the Governance Board of the National Network for Earthquake Engineering Simulation (NEES). Dr. Mejia has been a Lecturer of Geotechnical Earthquake Engineering at the University of California at Davis and an Extension Instructor in Geotechnical Engineering at the University of California at Berkeley. He was a member of the editorial board for the American Society of Civil Engineers Journal of Geotechnical Engineering and has been an invited keynote lecturer at multiple national and international conferences, and at professional and academic symposiums and meetings. Dr. Mejia served as a National Science Foundation (NSF) Panelist for the CAREER Program and other NSF research programs in Geotechnical and Geohazards Systems and has served on technical review boards for the United States Bureau of Reclamation, the United States Army Corps of Engineers, and the California Department of Water Resources on various dam projects, and for other owners on various engineering projects.
