Joshua D. McGraw — Nanofluidics and Interfacial Dynamics

The general interests in the Nanofluidics and Interfacial Dynamics JRC lab fall under the categories of soft condensed matter physics, nano- and micro-fluidic flows and pattern formation. Up to now in our research, investigations have related to polymer physics and fluid dynamics in confined environments. The topics range from the dependence of thin film properties on preparation conditions, to the effects of interfaces on polymer entanglement networks. Investigations also include the dependence of the slip boundary condition on the physical character of the solid-liquid interface, the effects of slip on micro- and nano-fluidic flows, and the effects of geometry and confinement on nanofluidic flows.
