Jürgen Janek

Jürgen Janek is full professor for Physical Chemistry at Justus Liebig University in Giessen (JLU), Germany, director of the JLU Center for Materials Research and Scientific Director of the BELLA lab at KIT, Karlsruhe.

He was visiting professor at Seoul National University (South Korea), Tohoku University (Sendai, Japan) and D'Aix-Marseille University (France), and has in 2025 become distinguished professor at Tohoku University in Sendai/Japan. He holds an honorary doctorate by TU Delft (Netherlands), is member of the Leopoldina – German National Academy of Sciences and was recently awarded with the first Greve Prize by Leopoldina.

He holds numerous patents, has published about 600 peer-reviewed papers and got numerous awards. His research interests focus on the physical chemistry of inorganic solids, solid state ionics and reactivity, specifically on the properties of mixed ionic-electronic conductors, defect chemistry of ionic materials, kinetics of solid-state reactions and solid-solid interfaces. In recent years his research is focused strongly on the chemistry of battery materials, solid electrolytes and solid-state batteries and operando studies of batteries. He is scientific coordinator of the German Cluster of Competence for Solid State Batteries FestBatt funded by BMFTR (Federal Ministry of Research, Technology and Space) and one of the spokespersons of the DFG Cluster of Excellence POLiS at Ulm University, Karlsruhe Institute of Technology and JLU Giessen.
