Professor Sholl's research focuses on materials whose macroscopic dynamic and thermo-dynamic properties are strongly influenced by their atomic-scale structure. Much of this research involves applying computational techniques such as molecular dynamics, Monte Carlo simulations and quantum chemistry methods to materials of interest. Current topics include: molecular transport through nanoporous materials, enantiospecific adsorption on chiral surfaces, and materials for hydrogen purification and storage. One thread running through all these topics is the development of accurate theoretical methods that can accelerate experimental study of problems where large numbers of potential materials need to be screened. Professor Sholl's work was the first to predict the remarkable properties of carbon nanotubes as gas separation membrane materials. These properties have recently been experimentally confirmed by several experimental groups. Similar predictions of new materials are now emerging from Prof. Sholl's modeling of metal alloy membranes for hydrogen purification and complex metal hydrides for hydrogen storage. In his work on chiral surfaces, Prof. Sholl is providing a theoretical underpinning for the fundamental mechanisms of current and future applications of enantioselective heterogeneous catalysis.

Self-assembled nanostructures in small-molecule and polymeric surfactants can be controlled through molecular design as well as processing flows, providing anisotropic structured fluids for templating nanoparticles that cannot self-assemble. Currently, understanding of the formation of nanocomposites is being used to develop applications in separation, delivery and protein stabilization. A second focus of Professor Walker's research is the impact of viscoelasticity on deformable interfaces under flow. Many industrial processes including ink-jet printing, spraying, and blending involve deformable liquid-vapor or liquid-liquid interfaces. Her work determines the role of fluid elasticity on these complex processes.
