Research Overview

The Laboratory of Interfacial and Small Scale Transport {LIS2T} specializes in problems involving interface-mediated transport and "interface sculpting" in systems ranging in scale from microns to nanometers. Current topical areas include the study of free surface instabilities and self-assembling structures in liquefiable films triggered by thermal, electrical, Marangoni or magnetic field modulation; intrinsic 3D lithographic patterning of nanofilms; layering transitions and symmetry breaking in nanofilms; fluid interface modulation for micro-optic, photonic and field emission micropropulsion systems;  non-normality and unstable flows at low Reynolds number; biological flows governed by Marangoni forces; development of a universal slip condition for liquid on solid flows; and study of breakdown regimes in continuum flow vs molecular dynamics simulations. We complement full scale experimentation with analytic work, numerical computations and non-equilibrium molecular dynamics simulations to develop physical insight for theoretical advances as well as reliable design principles for application driven work.
