Ewoldt named Fellow of Society of Rheology

Randy Ewoldt has been named to the 2025 class of Fellows of the Society of Rheology.

Fellowship in the society recognizes up to 0.5 percent of society members who demonstrate a history of distinguished scientific achievement, a significant technological accomplishment, and/or outstanding scholarship in the field of rheology.

Ewoldt was inducted for “pioneering new paradigms and resolving long-standing questions in the field of rheology, including design thinking for complex fluids, controlling the extensibility of yield-stress fluids, and elucidating the key experimental features and analytical underpinnings of protorheology. His overarching vision is that new engineering designs will result from a deeper fundamental understanding of rheologically complex materials.”

Ewoldt and his research group study rheology, non-Newtonian fluid mechanics, and design involving soft matter and complex fluids. His work involves experiments and mathematical modeling, and his overarching vision is that new engineering designs will result from a deeper fundamental understanding of rheologically complex materials. Recent motivating applications include direct-write 3D printing, wildland fire suppressants, hydraulic fluid power, stiffness-changing fibrous materials, medical task simulation, and flow batteries for grid-scale energy storage.

The 2025 inductees will be honored at the Society of Rheology Annual Meeting in October.

Ewoldt is the Alexander Rankin Professor in mechanical science and engineering.
