I am an Associate Professor in Engineering Science and a Tutorial Fellow at St Hilda’s College Oxford. Within EPG, my team's primary interest is in the modelling and management of electrochemical energy storage devices for automotive applications such as electric and hybrid vehicles, and also grid and off-grid power systems. We also have a small amount of research on electric machines. We develop novel instrumentation, diagnostics and modelling approaches that enable operation closer to performance limits, which is essential in order for these systems to reach commercial viability and make a positive impact on society and the environment. Our lab includes a range of battery test equipment, thermal imaging and calorimetry, data acquisation, scopes, 4Q power supply/loads, a dSpace battery simulator, and a 3D printer. Some examples of work include:

I studied engineering specialising in electrical and information sciences at Queens’ College, Cambridge University. After working as an engineering consultant, I undertook a PhD at Imperial College London on the subject of thermal design of electrical machines. Subsequently I worked as a post-doctoral researcher at Imperial on two automotive projects investigating electrically assisted turbocharging and advanced battery condition monitoring before being appointed at Oxford in 2011.
