Lukas Perret studied Power Systems Technologies at TU Clausthal for his Bachelor’s degree and received his Master’s degree in Energy and Process Engineering at TU Munich in 2020. He completed his bachelor's thesis at Siemens AG in reseach and development of large gas turbines in Mülheim/Ruhr, Germany and his master's thesis in process development of gas/liquid columns at Linde plc in Pullach near Munich. He started as a PhD student at the Institute of Catalysis Research and Technology at the Karlsruhe Institute of Technology (KIT). His research topic is embedded in the national BMBF project Kopernikus P2X and focuses on the process development of synthesis gas fermentation at elevated pressures.
