Summary
Electrochemical Science & Engineering
I am based in the Department of Mechanical Engineering and my research is based around fuel cell, battery and supercapacitor technology, and their application, mostly in transport. From the fundamental science to integration and systems engineering. The problems I investigate tend to emerge at the interface between the science and engineering. When a problem emerges in an application, to understand it better it is often necessary to drill back down again into the science, but always in the context of the application. Please see this article for more information.
