BACKGROUND
Enrique López Droguett joined the University of Maryland, College Park, in 2014. He conducts research on methods for probabilistic risk analysis and reliability of systems, uncertainty analysis, Bayesian methods, maintenance optimization, and ecological and biological risk assessment. He has led many major studies on risk and reliability of complex systems such as oil and gas exploration and production, oil refineries, commercial aviation, and hydropower plants. He has over 120 papers in refereed journals and proceedings of conferences and two books in various areas of risk, reliability engineering and maintenance.
