Dr George “Wren” Greene is a Research Fellow in the Institute for Frontier Materials at Deakin University in Australia. He received his PhD in Materials from the University of California, Santa Barbara in 2010. His expertise is in the physical chemistry of surfaces and interfaces which includes such phenomena as adhesion, friction, lubrication, self-assembly, and the interactive forces between matter at small length scales. His research interests cover a broad area that includes biotribology (i.e. biological adhesion and lubrication), biophysics, electrochemistry, solid-state electrolyte materials for energy storage and generation, and fluid-rock interactions important to geology.
