R&D Process Development Manager @ Umicore

Joris Roosen

Joris Roosen graduated as a MSc in Chemistry at the University of Leuven in 2008. He started a PhD at KU Leuven’s Chemistry Department on the recovery of critical metals from dilute aqueous waste streams by adsorption on functionalized biopolymers. After obtaining his PhD degree, he continued his research and lab coordination work in the same research group (under supervision of Prof. Dr. Koen Binnemans) for two more years. This allowed him to further build knowledge on the recycling and recovery of base and critical metals from secondary sources. Since 2018, Joris is employed at the R&D department of Umicore (Belgium) as a scientist in the Hydrometallurgy competence platform. There, it is his responsibility to coordinate several research projects, covering both the troubleshooting, debottlenecking, optimization and development of (new) hydrometallurgical processes. Joris has experience with the supervision of students and researchers. He likes to train coworkers and teach guest lectures at universities on different (hydrometallurgically related) topics.
