Hendrik (Henk) Verweij received his BS and MS degrees in 1975 from the Delft University of Technology, and his PhD in 1980 from Eindhoven Technical University. Until 1991, he was a research scientist at Philips Research Laboratories, where he studied the structure and formation of inorganic glasses, insulators, superconductors, and translucent ceramics. Verweij was a professor of chemical engineering at Twente University until 2000. In 2001, he moved from the Netherlands to the USA to become a professor at the Department of Materials Science and Engineering at Ohio State University (OSU). In 2018, he joined OSU’s Emeritus Faculty. Verweij’s expertise includes colloid and interface chemistry, solid state thermodynamics, sorption and transport in dense and porous matter, wet chemical and colloidal synthesis, and process control. His current research topics are inorganic membranes for CO2, H2, and O2 separation and water treatment, thin-film solid oxide fuel cells, and electrochemical O2 pumps.
