Dr. Efthymios Kantarelis studied Chemical Engineering at Aristotle University of Thessaloniki (Greece) from 2001 to 2006 and received his  Ph.D. at the Kungliga Tekniska Högskolan, Stockholm, Sweden, in 2014. He has been engaged in research at KTH Royal Institute of Technology since 2014 and has been an Associate Professor since 2018. Dr. Efthymios Kantarelis is a proud member of the Swedish Gasification Centre, Center for Production Utilization and Storage of Hydrogen (PUSH) and Chemical Reaction Engineering and Reactor Technology. His research interests lie within the field of Chemical Reaction Engineering and heterogeneous catalysis, with a main focus on the development and optimization of renewable processes and sustainable products. The design and analysis of the chemical reactors and processes (dynamic reactor models and control) are at the core of his research and are coupled with kinetics modelling in heterogeneously catalyzed systems (microkinetic and empirical LHHW models).
