Welcome to the Gollub Research Lab in the Department of Physics at Haverford College (also affiliated with the University of Pennsylvania).

We study nonlinear physical systems, particularly granular materials, particulates, and fluids. These systems produce striking patterns whose origins we seek to understand. Sometimes they give rise to chaotic dynamics or other forms of complexity.

Our work is supported by the National Science Foundation, Division of Materials Research under grant DMR-0405187. (disclaimer)
