Welcome to our website.
Please feel free to explore our website and learn more about what we do. The Laboratory for Complex Systems and Nonlinear Dynamics in Fluids and Granular Materials is directed and advised by Julio M. Ottino.
We are active participants in interdisciplinary research. Several PhD candidates and students in our group participated in the NSF-IGERT in Dynamics of Complex Systems in Science and Engineering as well as the NSF-IGERT in Virtual Tribology.
