Physical and Theoretical Chemistry

My research interests include many aspects of liquid-solid interface science, such as hydrophobicity, molecular mechanisms of lubrication, electrode interfaces with novel electrolytes, and bio-interfaces. In my laboratory we carry out experiments to detect how particles or surfaces interact across liquids. The aim is to reach a fundamental and molecular level picture of the physics whilst also selecting test-cases which have practical implications and applications. Over the past few years my research group has become particularly excited about a new class of liquids: ionic liquids. Some details of our current research in that area are below.
