The European Society of Rheology is open for everyone interested in rheology in all countries of Europe. Rheology is defined as the science of the deformation and flow of matter which means that rheology in some form enters almost every study of material properties. The ESR involves rheologists engaged in both industrial and academic research and development and is therefore a common meeting ground for engineers, physicists, chemists and biologists with a common interest in rheology.
 

Peter Fischer is the 2026 Weissenberg Awardee

Award Citation:
“For advancing rheology through pioneering, structure-informed methodologies that decode the complexity of food and biological soft matter and for establishing fundamental understanding across physiological function, sustainable systems, and processing-driven engineering.”

Peter Fischer studied Physics at the University of Regensburg and earned his doctorate in Physical Chemistry at the University of Essen in 1995. Following postdoctoral research at Stanford University, he joined ETH Zürich, where he has served as Professor of Food Process Engineering since 1998. Over nearly three decades, he has established an internationally recognized research program at the interface of rheology, soft matter physics, and food engineering.

Mazi Jalaal is the 2026 Oldroyd Early Career Awardee

Award Citation:
“For fundamental contributions to the rheology and flow of complex fluids with deformable interfaces, and for pioneering work in active and biological materials, Dr. Mazi Jalaal has made outstanding advances through the integration of theory, experiments, and computation, while bridging fundamental rheological physics with impactful real-world applications.”

After completing his Ph.D. in Rheology and Non-Newtonian Fluid Mechanics at the University of British Columbia under the supervision of Neil Balmforth and Boris Stoeber, Mazi Jalaal pursued postdoctoral research at the University of Twente with Detlef Lohse in Soft and Active Matter, and at the University of Cambridge with Raymond Goldstein in Cell Biology and Biophysics. He joined the Institute of Physics at the University of Amsterdam as Assistant Professor in 2021, was promoted to Associate Professor in 2024, and in 2026 began a joint appointment as Associate Professor at the Department of Applied Mathematics and Theoretical Physics (DAMTP), University of Cambridge.

Access to Rheologica Acta

Access to Rheologica Acta and Applied Rheology is free for all individual members of the ESR. Please access Rheologica Acta via the 'Member area'.

All participants of the AERC (or ICR) of the past year are automatically individual members of the ESR until the next AERC.

Rheologica Acta Publication Award

At every AERC or ICR, the editors of Rheologica Acta present the publication award sponsored by Anton Paar. This award gets selected by three editorial board members based on a preselection by the editors and is aimed to highlight the type of work which the journal likes to see published.

The 2025 Rheologica Acta Publication Award is given to: Panagiota Bogri, Gabriele Pagani, Jan Vermant, Joris Sprakel, George Petekidis: Orthogonal superposition rheometry of soft core–shell microgels, Rheologica Acta (2024) 63:705–717.

The entire list of the Rheologica Acta Publication Awards and the Weissenberg Lecture papers can be found in the Archive.
