Research

Arshad Kudrolli is a physicist and an experimentalist with an active research interest in soft matter, fluid dynamics, and applied mechanics. The systems he studies are typically nonlinear, driven, and far from equilibrium. Such systems display complex behavior and self-organization which often result from a few simple physical interactions between constituents. He has established the Complex Matter and Nonlinear Physics Laboratory and collaborates with researchers using experiments, simulations and theory to develop a deep understanding of such systems.

Current research topics include self-organization in chiral active matter, locomotion in granular matter, and erosion dynamics which shape Earth’s surface and subsurface. A second theme is on packing of structures and nonperturbative transformation of thin sheets towards making functional materials. He and his collaborators are also developing machine learning and data science methods to understanding long standing physical problems as in crumpling, and landscape dynamics driven by fluid flow.

Arshad Kudrolli has been named an Alfred P. Sloan Research Fellow by the Sloan Foundation, and is a recipient of a Research Innovation Award from Research Corporation and a CAREER Award from the National Science Foundation. He was elected Fellow of the American Physical Society in 2010. His research is funded by the National Science Foundation and the Department of Energy.
