Guy B. Marin





Guy B. Marin is emeritus professor in Chemical Reaction Engineering and founding member of the Laboratory for Chemical Technology (LCT) and the Center of Sustainable Chemistry (CSC) at Ghent University. He co-founded the spinoff AVGI in 2015.The investigation of chemical kinetics, aimed at the modeling and design of chemical processes and products all the way from molecular up to industrial scale, constitutes the core of his research. He co-authored two books, “Kinetics of Chemical Reactions: Decoding Complexity” with G. Yablonsky and D. Constales (Wiley-VCH, 2nd edition 2019) and “Advanced Data Analysis and Modelling in Chemical Engineering”, as well as more than 600 papers in high impact journals and is co-inventor in 8 filed patents. He is co-editor of the “Chemical Engineering Journal” and member of the editorial boards of “Industrial & Engineering Chemistry Research”, “Current Opinion in Chemical Engineering” and the “Canadian Journal of Chemical Engineering”. He is member of several International Scientific Advisory Boards and “Master” of the 111 project of the Chinese Government for overseas collaborations in his field.

Modelling Researcher


     Ismaël Amghizar

     +32 (0)472 24 72 18



Ismaël obtained a Masters degree in Chemical Engineering from Ghent University in Belgium. He then started a PhD programme, focused on kinetic and reactor modelling of steam cracking of hydrocarbons at the Laboratory for Chemical Technology of Ghent University. While finalising his disertation, he joined AVGI, where he works on developing and programming models to simulate steam crackers.

R&D Engineer
