Within our research group and the CampusLab Circular Economy, we offer a broad range of student research projects, Bachelor’s theses and Master’s theses related to nanoporous materials, aerogels, carbon materials, electrocatalysis, biorefinery and circular economy. If you are interested in joining our research activities for a project, Bachelor’s or Master’s thesis, please feel free to contact me directly. I am always happy to discuss possible topics.

Nanoporous Materials – From Sustainable Aerogels to Functional Carbon Materials and Circular Material Systems

My research focuses on the synthesis, processing and functionalization of nanoporous materials, with aerogels as a central material platform. A particular interest lies in understanding how precursor chemistry and processing conditions determine the microstructure of porous materials and how this structure can be tailored towards specific applications.

Biopolymer and sustainable aerogels
We develop aerogels from renewable and bio-derived precursors including cellulose, alginate, pectin, chitosan, proteins, lignin and natural biomass. Research covers the entire processing chain from gel formation and shaping to solvent exchange and supercritical CO₂ drying, with particular emphasis on controlling pore structure, particle morphology and material functionality.

Carbon aerogels and electrocatalysis
Biopolymer-derived aerogels also serve as precursors for highly porous carbon materials. Our research investigates the transformation of these structures during pyrolysis and their functionalization with catalytically active metals and metal oxides. A major focus is the stabilization and efficient utilization of noble-metal nanoparticles such as Pt and Ir/IrOₓ for electrocatalytic and hydrogen-related applications.

Supercritical processing and process development
Supercritical CO₂ technology connects material design with chemical engineering. We investigate supercritical drying and deposition processes, continuous and scalable aerogel production, and structure-preserving processing routes from laboratory synthesis towards larger-scale applications.

Biorefinery, sustainability and circular economy
A further focus is the integration of aerogel science with biorefinery concepts and circular economy principles. We investigate how biomass, industrial side streams and renewable feedstocks can be converted into high-value porous materials and how material design can be embedded into broader resource and process cycles. This includes the valorization of lignocellulosic feedstocks, the development of bio-based functional materials and the consideration of resource efficiency, material circularity and sustainable processing routes from the early stages of material development.

Across these areas, our aim is to establish structure–process–property relationships that enable the rational design of sustainable nanoporous materials for applications ranging from advanced functional materials to energy conversion and circular material systems.
