Executive Committee


PURPOSE: To provide leadership, advance the risk science, and promote the use of assessment and risk informed decision making.  To foster collaboration among civil engineering and other disciplines through program assistance and technology transfer.

Yumei Wang, P.E., F.ASCE, Chair
Vilas, Mujumdar, D.P.A., P.E., Dist.M.ASCE, Vice Chair
Bilal Ayyub, Ph.D., P.E., F.ASCE, Member
Keith Porter, Ph.D., M.ASCE, Member
Nasim Uddin, P.E., F.ASCE, Past Chair


Yumei Wang, leads the Geohazards team at the Oregon Department of Geology and Mineral Industries (, where her work focuses on lowering risks from earthquakes, tsunamis, and landslides. She is an advisor for the National Earthquake Hazards Reduction Program (NEHRP) and has taken part in post-earthquake damage assessments from Chile, China, and Sumatra earthquakes/tsunamis. Her current priorities include earthquake risk assessment of critical energy infrastructure, the design of North America's first tsunami shelter, and efforts to implement innovative policies to manage catastrophic Cascadia earthquake risks, including Oregon's unique seismic retrofit grant program. Wang has appeared on NewsHour with Jim Lehrer, and NOVA, National Geographic and Discovery documentaries. Wang served as Congressional Fellow in the U.S. Senate in Washington DC, and worked as a geotechnical consultant in California. She has an MS in Civil Engineering from the University of California, Berkeley and a BA in Geological Sciences from the University of California, Santa Barbara.

Vilas Mujumdar is a consulting engineer based in metro Washington area. For thirty five years, he was engaged in executive management in the private industry, and high-level administration in the public sector. In the private sector, he worked as Chief Executive Officer, President, & Partner in many engineering organizations. In the public sector, he served as Chief of Operations for the Division of the State Architect, State of California, & as the Program Director for Engineering Research Centers and for the Network for Earthquake Engineering Simulation (NEES) Programs at the National Science Foundation (NSF). His range of experience includes consulting engineering, project management, teaching, and research & research management. His focus is to integrate engineering and social science to reduce natural hazard risk to society.


Bilal M. Ayyub has 25 years of experience after the Ph.D. degree from the Georgia Institute of Technology in uncertainty modeling and analysis, risk analysis, and decision science. He completed several research projects that were funded by the National Science Foundation, Air Force, Coast Guard, Army Corps of Engineers, Department of Homeland Security, the Maryland State Highway Administration, the American Society of Mechanical Engineers, and several engineering companies. Dr. Ayyub is a fellow of ASCE, ASME and SNAME; has served the engineering community in various capacities through societies that include ASNE, ASCE, ASME, SNAME, IEEE-CS, and NAFIPS; and is the multiple recipient of the ASNE Jimmie Hamilton Award for the best papers in the Naval Engineers Journal in 1985, 1992, 2000 and 2003. Also, he received the ASCE Outstanding Research Oriented Paper in the Journal of Water Resources Planning and Management for 1987, the ASCE Edmund Friedman Award in 1989, the ASCE Walter Huber Research Prize in 1997, and the K. S. Fu Award of NAFIPS in 1995. The Department of the Army honored him with Army Commander’s Award for Public Service in 2007 for leading the development of the risk model for the hurricane protection system of New Orleans. Dr. Ayyub was appointed to many national committees and investigation boards. He has delivered many invited talks at leading national and international organizations including most recently a distinguished lecture to the Brazilian Research Agency, the Department of Homeland Security, Naval War College for the Chief of Naval Operations, the Army Corps of Engineers, and the Australian national Marine Safety Committee.


Keith Porter specializes in seismic vulnerability and 2nd-generation performance-based earthquake engineering. He is the Principal Investigator on a $1M project for the Global Earthquake Model ( to develop standard procedures for modeling the seismic vulnerability of buildings anywhere in the world. With researchers at the Pacific Earthquake Engineering Research (PEER) Center, he developed a second-generation performance-based earthquake engineering (PBEE-2) methodology that measures probabilistic building performance in terms of dollars, deaths, and downtime. He participated in a FEMA-funded effort (ATC-58) to bring that methodology to professional practice. He coordinated the estimation of physical damages for the USGS’s M7.8 Southern California earthquake scenario (more detail here), its California winter storm (“ARkStorm”) scenario (detail here), and tsunami scenario (in progress). Other current and recent research includes demand surge, seismic reliability of critical facilities, estimation of downtime in critical facilities; and a benefit-cost analysis for the US Congress and the Multihazards Mitigation Council that found FEMA-funded disaster mitigation to save $4.00 for every $1.00 spent. Dr Porter previously worked on the research faculty at the California Institute of Technology in Pasadena, California. He is a licensed Professional Engineer with experience in construction contracting (Continental Heller Corp., 1986-1987), structural design (TY Lin International, 1987-1988), and risk analysis of natural disasters (EQE International, 1990-1997). He is Principal of the international risk consulting company SPA Risk LLC (2004- ).


Nasim Uddin has 20 years of experience following the Ph.D. degree from the State University of New York (SUNY) at Buffalo, in seismic modeling and analysis, multi-hazard analysis, and high performance infrastructures. He is a professor of civil engineering in the University of Alabama at Birmingham teaching Wind & Seismic Load, Advanced Steel Structures, and Bridge Engineering. He is a leading researcher in the field of disaster resistant panelized construction and bridge infrastructure safety; and is currently leading an international research with European partners on next generation Bridge Weigh-In-Motion (BWIM) System to effectively manage the nation’s aging bridge infrastructure, and high performance infrastructure against flood, blast, and hurricane resistant design. He completed several research projects that were funded by the National Science Foundation, Department of Transportation, Federal Highway Administration, University Transportation centers, and Alabama Department of Transportation whose cumulative funding exceeds $7.0 million, and directed numerous Doctoral and Master's theses based on the sponsored research projects. Dr. Uddin is the author/co-author of 5 books, over 150 publications, and CDRM monographs including Disaster Risk Assessment and Mitigation (New York: ASCE, 2008), Windstorm and Storm Surge Mitigation (New York: ASCE, 2010), Blast Protection of Infrastructures and Vehicles using Composites (London: Woodhead Publishing, 2010), Quantitative Risk Assessment for Natural Hazards (New York: ASCE, 2011), and Developments in Fiber Reinforced Polymer (FRP) Composites for Civil Engineering (London: Woodhead Publishing, 2013). Dr. Uddin received NSF Grants to organize an international workshop on wind storm and Storm Surge Mitigation Construction, in Dhaka, Bangladesh. Dr. Uddin was appointed to many technical committees, and he has delivered many invited talks at leading national and international organizations. He is a Faculty Fulbright Scholar, a fellow of ASCE and past Chair of the Executive Committee of the ASCE Council on Disaster Reduction Management (CDRM).
