Louis de Smet obtained his PhD degree from Wageningen University in 2006 on the topic of covalently attached organic monolayers on silicon surfaces. After postdoctoral work at the Ian Wark Research Institute (Adelaide, Australia) on biocompatible polymer coatings he was awarded an NWO Veni Grant to study molecular interactions involving polysaccharides. In 2007 he joined TU Delft (NL) as an Assistant Professor to teach Chemical Thermodynamics and to start a research group on organic coatings, mainly to detect volatile organic compounds and ions in water. In 2016 he was appointed as an Associate Professor at Wageningen University where he now teaches Analytical Chemistry. His research group is part of the Laboratory of Organic Chemistry and focuses on the preparation and characterization of organic materials for ion sensing, ion separations and ion recovery, for which he was awarded an ERC Consolidator Grant. Since 2017 he also serves as a Senior Advisor to Wetsus (Leeuwarden, The Netherlands) on organic materials for sustainable water technology.
