Manuel Delgado is an Associate Professor at the Faculty of Sciences of the University of Porto. He obtained his PhD degree and Aggregate title in Mathematics in 1997 and 2006, respectively. He was Director of the Research Centre in Mathematics of the University of Porto (CMUP) during 2013-2016 and is currently responsible for CMUP's Computational Mathematics research area. He was the Director of the joint PhD program in Mathematics of the Universities of Coimbra and Porto during the years 2020 and 2021. He supervised 1 PhD thesis and 3 MSc dissertations. His research interests moved from a relatively pure area of finite semigroups, with applications in theoretical computer science, to numerical semigroups, an area with some important known applications (namely in codding theory). He published about 25 papers in journals and some book chapters. He is interested in open-source mathematical software in the areas he does research: among the GAP packages made public, one on finite state automata and another on numerical semigroups are refereed GAP packages.
