Ahmed has more than 24 years of experience in earthquake engineering and multi-hazard risk assessment. He specializes in probabilistic assessment of natural hazards and their impact on infrastructure systems and is experienced in leading teams of multi-disciplinary experts on complex projects.

Areas of his technical expertise include multi-hazard reliability assessment of large geographically dispersed infrastructure systems such as water transmission and distribution systems, specialized analysis and design of heavy civil infrastructure such as water tanks, dams, large diameter pipelines and massive concrete structures.

He has developed earthquake design criteria for critical onshore and offshore oil and gas facilities, water systems and major buildings such as the Oakland City Hall and New Zealand Parliament Building. Ahmed has performed research studies for the National Science Foundation (NSF), Building Seismic Safety Council (BSSC), California Divisions of Mines and Geology (CDMG) and California Department of Transportation (CalTrans). He is a contributing author of ASCE special publication on seismic design and evaluation of petrochemical facilities and NIST (National Institute of Standards and Technology) publication on reliability and restoration of water supply systems for fire suppression and drinking following earthquakes. He has numerous technical publications related to earthquake engineering and reliability assessment of infrastructure systems.
