Process Systems Engineering

Major research interests

The focus of my research is on the model-based analysis, synthesis, operation and control of complex process systems in chemicals production, energy conversion and biotechnology. A key element for sustainable process design is the Elementary Process Functions (EPF) methodology which is continuously developed in the Sundmacher group, with consideration of all decision variables on the main levels of the process hierarchy, i. e., the molecular level, phase level, process unit level, plant level, and the “Verbund” level. Applications in chemicals production include gas phase processes, integrated processes in liquid multiphase mixtures, and multidimensional crystallization processes. In the area of energy conversion processes, the current major interests are the multiscale investigation of water electrolysis cells for hydrogen production and the optimal design of power-to-X processes. The most important research activities in biotechnology are in the design and dynamic operation of microalgae-based biorefineries, as well as in the bottom-up synthesis of artificial cells from functional molecular modules. In all these projects mathematical modeling, computer-aided approaches and experimental validation methods are closed combined.
