Research Description

The overarching theme of my research is the theoretical description and molecular dynamics simulation of interfaces. My primary focus is on the curvature-dependent properties of interfaces. Major projects include the peptide solubilization of carbon nanotubes, the behavior of nanoparticles in fluids and at fluid Interfaces, and the free energy of phase transformations between different lipid self-assemblies. In addition, I develop new simulation tools including multiscale modeling algorithms.
