Introductory Plenary Lectures 2019

We were happy to have the following plenary speakers for MODEGAT VI:


Prof. Petr Kočí, University of Chemistry and Technology, Prague, Czech Republik

Associate professor at University of Chemistry and Technology, Prague (UCTP), Department of Chemical Engineering. His research interests include multi-scale mathematical modeling of transport, reactions and transformations in porous catalysts and filters with applications in automotive exhaust gas conversion. Petr Kočí obtained his Ph.D degree in Chemical Engineering at UCTP in 2005. He has published about 50 papers in impacted scientific journals and worked on research projects with several academic and industrial partners, including Oak Ridge National Laboratory, Daimler, Johnson Matthey, Ecocat, Umicore and Corning.

Plenary talk title: Multi-scale modeling of catalytic particulate filters for gasoline engines (GPF)


Prof. Grigorios Koltsakis, Aristotle University, Thessaloniki, Greece

Dr. Grigorios Koltsakis received his Diploma and Ph.D from the Department of Mechanical Engineering of Aristotle University of Thessaloniki. He is currently a Professor at the Laboratory of Applied Thermodynamics of Aristotle University, specializing in Internal Combustion Engines and exhaust after-treatment technology. He has authored more than 100 papers in scientific Journals and international conferences and holds 2 patents. Dr Koltsakis has received the Arch T. Colwell Merit Award as well as two Oral presentation awards from SAE International. He has also received the first Innovation prize from the Research Committee of Aristotle University. Dr Koltsakis leads a research group active in the simulation and evaluation of after-treatment technologies in close collaboration with the international automotive industry. He is a co-founder and scientific director of Exothermia SA, a University spin-off company developing emission control system simulation software.

Plenary talk title: Challenges and model-based solutions in SCR-coated filters applications

Dr. Ton V. W. Janssens, Umicore Denmark, Kgs  Lyngby., Denmark

Dr. Ton V. W. Janssens pursued an education in Chemical Engineering at the University of Technology Eindhoven (NL) and obtained his Ph.D from the same university, in a collaboration project with the University of Bonn(D), studying the electrostatic effects of alkali promoters on a Rh(111) surface. He has spent 2 years at the University of California, Riverside and 1½ year at the Fritz Haber Institute, in Berlin, working on reactions of hydrocarbons on Pt and Pd surfaces. Having joined Haldor Topsøe A/S in 1998, he mainly worked on the development of catalysts for hydrogen production, Au catalysts, and methanol-to-gasoline processes. He then changed to the automotive department at Topsøe in 2012 and shifted his focus to NH3-SCR and ammonia slip catalysts. In 2017, he followed the transfer of the Topsoe automotive catalysis to Umicore Denmark, continuing the work on automotive catalysis for heavy-duty diesel vehicles.
