Polymer membranes are essential components in a wide range of applications, from water treatment and chemical separations to electrochemical energy conversion. Their performance depends critically on the choice of material system, membrane geometry, and processing conditions. In our research group, we develop novel polymer-based membrane materials that combine high chemical and thermal stability with tunable material properties, designed to perform reliably even under demanding operating conditions where conventional membranes often fall short.

A particular focus lies on hollow fiber membrane geometries, which offer a high surface-area-to-volume ratio and compact module design, making them especially attractive for water treatment, gas separation, and chemical processing. Beyond membrane geometry, we also explore the application of novel polymer systems in anion exchange membranes (AEMs) for electrochemical energy conversion. AEM-based fuel cells and water electrolyzers can operate with earth-abundant, low-cost catalysts, offering a scalable pathway for the energy transition. However, the long-term stability under harsh alkaline conditions remains a key challenge that drives our material development. Alongside these application-driven directions, we are equally committed to improving the sustainability of membrane materials by exploring bio-based polymer systems derived from renewable resources, combining reduced environmental impact with the high chemical, thermal, and mechanical stability required for demanding separation applications.

The scope of each project can be adapted to a Bachelor's or Master's thesis, as well as research internships. The start date is flexible.
