Roseanna N. Zia has been named a 2025 American Physical Society (APS) Fellow.
The honor recognizes Zia’s pioneering contributions to the physics of soft and biological matter, including the development of colloidal models that reveal the physical principles governing intracellular transport and whole-cell dynamics.
Zia is the Dave Wollersheim Professor of Mechanical and Aerospace Engineering. She is also a recipient of two Presidential Early Career Awards for Scientists and Engineers. Her work 3D diffusion of ribosome-sized particles in live Escherichia coli cells was recently published in the Proceedings of the National Academy of Sciences.
The Zia Research Group unifies mesoscale physics and chemistry with cellular-level biology through novel theoretical modeling and large-scale computational simulations.
The APS Fellowship Program was created to recognize members who may have made advances in knowledge through original research and publication or made significant and innovative contributions in the application of physics to science and technology.
