Specific Interests: Complex liquids, fluid dynamics, multiphase flow, gelation and jamming of colloidal solutions, and surface tension induced instabilities. In our lab we study the non-linear dynamics of a wide variety of systems. In colloidal solutions, using light scattering methods, we examine how solidification/gelation occurs in weakly attractive colloidal suspensions. We also investigate, using PIV flow imaging, the particle dynamics and flow instabilities that occur when fluid passes through a collection of settling or fluidized spheres. Thermal (IR) imaging methods allow us to investigate the Marangoni instability induced by evaporative cooling from volatile liquids.
