Katherine Collett

Dr Katherine Collett is a Postdoctoral Researcher in the Energy and Power Group at the Engineering Department and a Fellow of the Oxford Martin Programme on Integrating Renewable Energy.

After receiving a first class integrated Masters degree MEng in General Engineering from Durham University, where she specialised in renewable energy, Katherine completed a DPhil in the Materials Department at the University of Oxford. Her research focused on improving silicon surface passivation using low-cost, readily available processing techniques for use on high efficiency solar panels.

Katherine is interested in addressing the cross-disciplinary challenges associated with transitioning towards zero-carbon energy systems and the technical advances that make this economically appealing.

She has spent time researching a breadth of technologies to better understand the interplay of different clean generation sources, such as wind power, nuclear fusion and solar.

At present, Katherine is working on the Innovate UK funded project ‘Vehicle-to-Grid Oxford’. The project aims to identify possible business models associated with using electric vehicle batteries for energy storage and other electricity grid balancing services.
