Gollub's research is in the general area of Nonlinear Physics, which is concerned with the mesoscopic and macroscopic behavior of complex systems. Often these systems are described by nonlinear partial differential equations such as the Navier-Stokes equations of fluid motion. His group has conducted experimental work on the following topics over the years: hydrodynamic instabilities and the transition to chaos and turbulence in fluids; the dynamics of nonlinear waves, turbulent convection induced by thermal gradients; thin film flows; and mixing in fluids. Current and recent projects include problems related to spatiotemporal chaos, particle dynamics in fluids, experiments involving microfluidic flows, the dynamics of granular materials, and the physics of swimming microorganisms. Many Haverford students, postdoctoral associates, and visitors have participated in these projects. A publication list may be accessed from my Homepage.
