Professor Mathias Wessling from RWTH Aachen University in Germany, winner of the Leibniz 2019 price, is innovating four pillars of membrane technology: 1-hollow fiber NF, 2-layer by layer membranes, 3-AI backward design recipes, and 4-water treatment inverse problems. We (Rhea Verbeke and I) talked about the contributions of his research that have been made it from lab scale to pilot scale to industrial products.  His membrane innovations are either licensed to companies such as Evonik or transformed into new companies such as Con-vergence, furthr-research, Amovion and Biothrust. Currently, his team is developing a novel membrane for dialysis that has thepotential to shift the dialysis market. Enjoy this episode that bridges valuable insights for academics, industrial experts and investors active in water field and beyond!
