We study how liquids interact with solid surfaces and how they behave in nano-scale films or pores. Of particular interest are liquids with a high ion density: concentrated electrolytes and ionic liquids. The aim is to solve problems and generate greater understanding relevant to a range of applications including energy storage, lubrication, adhesion, and nanomaterials.
