Roland Kádár

Universitetslektor at Chalmers, Industrial and Materials Science, Engineering Materials

Roland’s research lies at the confluence between fundamental science and applied research in polymeric materials and composites. Namely, he is investigating the relationship between the rheological properties and the linear and nonlinear flow dynamics of complex materials to understand the interplay between their molecular structure, processing and performance. Furthermore, the development of advanced rheological characterization techniques is also pursued. In addition to his activities at Chalmers, Roland is cooperation partner at the Karlsruhe Institute of Technology (KIT) in Germany and is editor of the Annual Transactions of the Nordic Rheology Society.
