Craig A. Davis, Ph.D., PE, GE TCLEE Chair is the Geotechnical Engineering Manager for the Los Angeles Department of Water and Power, Water System (LADWP) and is responsible for managing geotechnical engineering, contract management, and project management groups for LADWP geotechnical projects and overseeing a $700 million dam and reservoir development program and the Water System seismic improvement program.  He is a California licensed Civil and Geotechnical Engineer and received a B.S. in Civil Engineering from the California Polytechnic State University in San Louis Obispo, CA, an M.S. in Civil Engineering with emphasis in structural earthquake engineering from the University of Southern California in 1991, and a Ph.D. in Civil Engineering with emphasis in geotechnical earthquake engineering from the University of Southern California in 2000.  He has worked for the LADWP since 1987 where he has investigated and evaluated numerous dams, managed several multimillion dollar projects, and implemented unique and innovative designs. Dr. Davis is actively involved in earthquake, geotechnical, and lifeline engineering research, developing a number of case studies from the 1971 San Fernando CA, 1994 Northridge CA, 2011 Christchurch NZ, and 2011 Tohoku JP earthquakes and performing evaluations on the seismic performance of dams and reservoirs, pipelines and underground structures, the effects of ground deformations on water system facilities, and seismic resiliency of lifeline systems.  Dr. Davis has published over 75 papers in technical journals and conference proceedings and has co-organized national and international workshops on water systems and earthquake related aspects.  He is on the executive committee for the ASCE Technical Council for Lifeline Earthquake Engineering (TCLEE) and the Lifeline steering committee for the California Strong Motion Instrumentation Program.  Dr. Davis is an adjunct professor at the Beijing University of Civil Engineering and Architecture and works with the Earthquakes and Megacities Initiative, an international not-for-profit organization as an expert in water lifeline networks.

Jamie E. Padgett is an Assistant Professor in the Department of Civil and Environmental Engineering at Rice University in Houston, TX. She received her B.S. from the University of Florida and M.S. and Ph.D. from the Georgia Institute of Technology in Civil Engineering. Padgett’s research focuses on the application of probabilistic methods for reliability and risk assessment of structures and infrastructure. Her work addresses the protection of bridges exposed to multiple hazards, such earthquakes, hurricanes or aging and corrosion, as well as the use of advanced materials for structural retrofit and rehabilitation. Padgett’s research offers models to quantify and promote infrastructure sustainability while enhancing safety under multiple hazards. She is Chair of the ASCE technical sub-committee on Multiple Hazard Mitigation, and an active member of several national technical committees, including the Structural Engineering Institute’s Technical Council on Life-Cycle Performance, Safety, Reliability, and Risk of Structural and Infrastructure Systems, and ASCE’s Technical Committee on Seismic Effects. She currently serves on editorial boards for the Journal of Bridge Engineering, Earthquakes and Structures, and Natural Hazards Review. Padgett has received several awards and recognitions including the 2011 National Science Foundation Faculty Early Career Development (CAREER) Award and the ASCE 2009 New Face of Civil Engineering for her contributions to the field of infrastructure risk assessment and protection. Her research has been supported by such agencies as the National Science Foundation, Transportation Research Board, and Houston Endowment. 

 

Dr. Kent Yu, Ph.D., P.E., S.E. is Principal of SEFT Consulting Group located in Portland Oregon.  He is best known for his use of advanced analysis and performance-based earthquake engineering.  A seismic veteran, an earthquake/tsunami policy advocate, and member of SEAO, ASCE TCLEE and EERI, Dr. Yu has traveled to Peru (2007), China (2008), Chile (2010), and Japan (2011) for post-earthquake reconnaissance to study seismic performance of buildings and lifeline structures. He applies state-of-art technology and lessons learned from recent earthquakes to his building and lifeline projects to ensure that the buildings are safe and critical services remain protected after an earthquake.  He served as the Chairman of the Oregon Seismic Safety Policy Advisory Commission (OSSPAC) from 2011 to 2013, and led an expert team of 169 volunteers in the development of an ambitious 50-year resilience plan to help prepare Oregon to withstand and recover from a M9.0 Cascadia earthquake and tsunami.   He is a member of the ASCE 7 Subcommittee on Tsunami Loads and Effects which is responsible for developing a national standard for tsunami design of buildings and other structures.  He continues his involvement in earthquake engineering and tsunami debris impact research as adjunct professors at Portland State University and Oregon State University, respectively.  Over the years, Dr. Yu has received numerous recognitions, including “40 Under 40” by Building Design + Construction magazine (2008) and “Engineer of the Year” by ASCE Oregon (2012). 

 

Nason McCullough, Ph.D., P.E. TCLEE Chair, is a senior technologist and geotechnical engineer with CH2M HILL in Corvallis, Oregon, and is a courtesy faculty member at Oregon State University’s Department of Civil and Construction Engineering. Nason has been involved in the geotechnical and seismic design of many types of structures and facilities with CH2M HILL, primarily embankment dams and waterfront and port facilities in the United States and internationally. Nason has a bachelor of science, masters of science, and doctor of philosophy in civil engineering, focusing on geotechnical engineering. He is a registered professional engineer in Oregon. He is very active as a member of ASCE; as a member of the executive committee for the Technical Council on Lifeline Earthquake Engineering (TCLEE), chair of the TCLEE ports and harbors committee, member of the TCLEE post-earthquake reconnaissance committee, and a member of the Coastal, Ocean, Ports, and River Institute (COPRI) standards committee developing seismic design guidelines for pile-supported piers and wharves. Nason was involved in the post-storm investigation following the December 2007 Pacific Northwest storms and the January 2010 Haiti Earthquake. In 2009 he was awarded the TCLEE Honor award.
