Dr. Joost Santos is an associate professor in the Department of Engineering Management and Systems, The George Washington University Engineering. He received his Ph.D. in Systems Engineering at the University of Virginia in 2003, with distinction (Louis T. Rader Outstanding Ph.D. Student). Following his Ph.D., Prof. Santos held a research faculty position at the University of Virginia’s Center for Risk Management of Engineering Systems. Dr. Santos is one of the key developers of the inoperability input-output (I-O) model, which utilizes and transforms economic I-O accounts for disaster risk management applications. This model has been applied in scenarios such as hurricanes, disease pandemics, and electric power blackouts, as well as in the evaluation of renewable energy options. Results of his research activities are documented in more than 50 peer-reviewed publications, including a highly cited article on modeling system interdependencies that appeared in an issue of Risk Analysis in 2004. He won two best paper awards from the Society for Risk Analysis. He was also the 2009 recipient of the Leontief Memorial Prize from the International Input-Output Association. Dr. Santos is a recipient of several grants from the National Science Foundation, which aim to develop infrastructure preparedness models to minimize disaster impacts on interdependent systems. Dr. Santos has also received grants from the American Society for Mechanical Engineers, George Washington Institute of Public Policy, and George Washington Institute for Biomedical Engineering. In 2013, he has been inducted to the Philippine-American Academy of Science and Engineering. He collaborates actively with a research group from De La Salle University (Philippines) to extend the I-O models to disaster management and energy applications.
