Dr. Santos-Reyes is a lecturer at Instituto Politécnico Nacional, Mexico. He was awarded a Ph.D. from Heriot-Watt University, UK, in 2001. On completion of his Ph.D., he conducted 3-year post-doctoral research at the same university. He developed a systemic disaster management system model, which has been employed extensively to the analysis of past disasters. His main research interests are modelling safety management systems, diagnosing systems failure, technological and natural hazards risk perception, accident and risk analysis (e.g., mass transit transport systems such as metro, BRT, among others.), past disaster analysis (floods, earthquakes), critical infrastructure interdependence modelling, human reliability analysis (e.g., bus, BRT, train drivers), public transport drivers fatigue, human stampede disasters, futures scenarios.
