Research Interests

In interfacial science, there is an unprecedented opportunity to create new assemblies and devices on the micro- and nanoscale. At these length scales, surface to volume ratios are large, and control over interfacial properties is key to the success of these endeavors. My group is creating powerful approaches to control any micro- & nanoscale system by developing a better understanding of how we can manipulate interfacial properties, either externally via the use of a stimulus or internally via the design of surface structure. More specifically, our research objective is to elucidate the role played by an electric field or surface structure (or both) in modulating interfacial properties such as wetting or adhesion. Using approaches from the molecular to the macroscale, we provide a mechanistic understanding of the phenomena at play.
