معرفی
Urs Gasser is a Senior Scientist at the Paul Scherrer Institute (PSI) in Switzerland, working within the Laboratory for Neutron Scattering and Imaging. His research focuses on experimental physics with emphasis on soft condensed matter systems, utilizing advanced scattering techniques to investigate fundamental properties of soft materials.
His educational background includes undergraduate studies in physics at ETH Zurich (1990-1995), PhD studies at ETH Zurich and PSI (1995-1999), postdoctoral research at Harvard University (1999-2001), research assistant position at University of Konstanz (2002-2005), and habilitation in Experimental Physics at University of Konstanz (2016).
Gasser's research centers on soft condensed matter physics, particularly the behavior of polymers and colloidal suspensions where constituent interactions depend on size, surface properties, geometrical shape, and solvent characteristics. His work explores crystal nucleation in colloidal systems, interactions of soft colloidal particles, phase behavior of magnetic/non-magnetic colloid mixtures, and morphology of grafted copolymer membranes for fuel cells. He primarily employs small-angle neutron and X-ray scattering, light scattering, and optical microscopy as investigative tools.
Analysis of his recent publications reveals a consistent focus on microgel systems, with particular attention to counterion effects, deswelling phenomena, mechanical properties, and phase behavior. His work bridges fundamental soft matter physics with practical applications in energy materials, particularly fuel cell membranes. The publications demonstrate expertise in advanced scattering techniques to probe nanoscale structures and dynamics in soft materials.
Gasser has been a Senior Scientist at PSI's Laboratory for Neutron Scattering since 2005, with previous research appointments at Adolphe Merkle Institute (University of Fribourg), University of Konstanz, and Harvard University. His research program connects fundamental soft matter physics with practical applications in energy technology, particularly through investigations of polymer membranes for fuel cells.
