Stefan Salentinig is a physical chemist with a PhD in bio-colloids and scattering methods from the University of Graz, Austria in collaboration with an international partner in the food industry (2010). His research interests lie in the rational design and development of bioinspired materials for functional foods, drug delivery and diagnostics. He has strong expertise in the design and application of advanced experimental methods including X-ray and neutron scattering, electron microscopy and spectroscopy on lab and large-scale research infrastructure to study material composition, nanostructure and function.
After experience in the medical products industry as R&D project manager in surface coatings, he relocated to Australia in 2011 to take on a research scientist position in material science focusing on separation technology for energy applications at the Commonwealth Scientific and Industrial Research Organisation (CSIRO). In 2013 he joined Monash University in Melbourne as a research fellow in the Department of Pharmaceutical Sciences, designing nanoscale drug delivery systems and researching the digestion of food emulsions. In 2015, he joined the Swiss Federal Labs, to head the Biomolecules at Surfaces group, pursuing research on the design of functional nano-biointerfaces for health applications based on molecular engineering approaches.
Since 2019 he is professor in experimental physical chemistry at the University of Fribourg’s Department of Chemistry. His group has well- established collaborations with leading research institutions and industry partners, including ETHZ and PSI (Switzerland), the University of Copenhagen (Denmark), TU Graz (Austria), the University of Pernambuco (Brazil), the University of Umea (Sweden), NTU (Singapore).
Our group in Biocolloids aims at understanding some of the fundamental principles in colloid and interface chemistry related to food and antimicrobial systems. We study natural colloids and interfaces such as milk as functional food material or antimicrobials to get inspired and guided by design strategies that have been optimized by evolution over millions of years. Ultimately, we envision novel multi-functional materials with broad impact in food science and nutrition as well as drug delivery.
The group pursues research interests that include (directed) self-assembly and disassembly processes for the bottom-up creation of new supramolecular food and drug delivery materials, and adaptive, programmable bio-nanointerfaces. We are also interested in the modification and integration of scattering, spectroscopy and microscopy techniques to advance the comprehensive design and characterisation of material interactions across boundaries - on the molecular, structural and the cellular level.
