Walid Abdala Rfaei Jradi received his bachelor degree in Data Processing from the Instituto Unificado de Ensino Superior (IUESO) in 2005, his master degree in Computer Science in 2008 and his Ph.D., also in Computer Science, from the Universidade Federal de Goiás in 2016. During his graduation, he developed a study on modeling and simulation of sewage and rainwater collector networks. He also developed studies on the traveling salesman problem to optimize a system for the distribution of goods for a transportation company. In his master degree, he proposed and developed a Web-Based traffic simulator suited to the way traffic behaves in Brazilian urban road networks. During his Ph.D., he conducted studies and proposed GPU-based parallel algorithms and implementations for the problem of macroscopic assignment of urban traffic on large-scale networks. He also worked on some genetic algorithms aimed to the problem of to two-dimensional guillotine cutting. Among the areas of interest are Parallel Computing, Graph Theory, Combinatorial Optimization, Formal Languages and Automata, DataBases, Artificial Intelligence, Discrete Mathematics and Operational Research.
