Our research centers on phenomena on the micro and nanoscale. We are particularly interested in the adsorption of surfactants at fluid interfaces and their influence on interfacial flows, colloidal hydrodynamics, microfluidic phenomena as it relates to lab on a chip platforms for diagnostic assays and biosensing, the microhydrodynamics of spreading, hydrodynamic slip at an interface and the dynamics of colloids at a fluid-fluid interface. Our group studies these phenomena both experimentally – using transmission, fluorescence and confocal microscopy for visualization of the motions of droplets and colloids,and soft lithography for the fabrication of transparent microfluidics cells and diagnostic assaying - and theoretically using continuum and molecular dynamics simulations. Specific problems currently under study include multiphase flows in narrow capillaries, mass transfer from moving fluid droplets, thin film instabilities, and biomembrance deformation phenomena.
