Rafael Holdorf Lopez


Rafael Holdorf Lopez is a Professor in the Department of Civil Engineering at the Federal University of Santa Catarina, Brazil, since 2011. He obtained his undergraduate degree in Civil Engineering from the Universidade Tecnológica Federal do Paraná (Brazil), in 2006, and received his PhD in Mechanical Engineering from the Institut National des Sciences Appliquées de Rouen (France) in 2010. Currently, Dr. Lopez has a Level 2 CNPq Researcher Fellowship and conducts research on the development of algorithms for engineering optimization and optimization under uncertainty, reliability and uncertainty quantification, with applications to structural systems.
