Dr. Behringer's research interests include granular materials: friction, earthquakes, jamming; nonlinear dynamics; and fluids: Rayleigh-Benard convection, the flow of thin liquid films, porous media flow, and quantum fluids. His studies focus particularly on experiments (with some theory/simulation) that yield new insights into the dynamics and complex behavior of these systems. His experiments involve a number of highly novel approaches, including the use of photoelasticity for probing granular systems, innovative experiments to characterize the stability of surface flows and properties of gels, and magnetic resonance imaging to study flows in porous media.
