Cristel Pelsser

Critical embedded systems, Computer networking, Researcher, Professor




Cristel Pelsser holds a chair in critical embedded systems at UCLouvain. From 2015 to 2022 she was a full professor at the University of Strasbourg (France) where she led a team of researchers focusing on core Internet technologies. She spent nine years as a researcher working for ISPs in Japan. Her aim is to facilitate network operations, to avoid network disruptions and, when they occur, pinpoint the failures precisely in order to quickly fix the issues, understand them in order to design solutions to prevent recurrence. Cristel received the PhD degree from the Université catholique de Louvain (UCLouvain), Belgium.
