Dr. Roberto Ley-Borrás has M.Sc. and Ph.D. degrees in Engineering-Economic Systems from Stanford University (California) with concentration in Decision Analysis, a M.Sc. in Industrial Engineering from Lehigh University (Pennsylvania) with concentration in Operations Research and a B.Sc. in Industrial Engineering from Orizaba Technological Institute (Mexico). At Stanford University he coordinated during four academic terms the Decision Analysis Seminar directed by Ronald A. Howard.

He was a full professor at Orizaba Technological Institute for twenty years and founded and directed the Decision Analysis concentration of the Industrial Engineering graduate program. He was a member of the National System of Researchers of Mexico and served at numerous academic committees at the national level. He has also taught decision analysis at Argentina and Spain. In addition, he has served in a number of positions in industry and the public sector.

Dr. Ley-Borrás has made scholarly contributions in the fields of decision analysis, probabilistic forecasting and modeling of uncertainty. His works include the development of the Reusable Decision Models approach that provides a more efficient analysis of families of decision situations, a method for measuring the amount of relevance (probabilistic dependence) among probabilistic nodes in influence diagrams, a probabilistic method based on Markovian models for forecasting conflict outcomes (the method was the first in its class and successfully empirically tested), an integral process for decision analysis that is efficient and comprehensive (Integral Decision Analysis), an approach for generating and selecting the decision situation (a key step in decision analysis) and an approach to assess the quality of the decision analysis process before the decision is implemented.

He has published in international peer-reviewed journals and is the author of the books Integral Decision Analysis (Análisis de Decisiones Integral) and Uncertainty and Risk Analysis for Decision Making (Análisis de Incertidumbre y Riesgo para la Toma de Decisiones), both being used by universities and consulting firms in Latin America and Spain.

Currently he is Director of Consultoría en Decisiones (decidir.org) and provides consulting and training in decision analysis to firms and institutions. He has worked with universities, private businesses, the National Petroleum Institute (Mexico), the Electric Research Institute, Petróleos Mexicanos (Pemex) and the World Bank.
