Since February 2014 I have been director of The Energy Future Lab at Imperial with responsibility for facilitating interdisciplinary research and postgraduate education in energy and in coordinating its dissemination. I remain Deputy Head of the Department of Electrical and Electronic Engineering. I lead the EPSRC hub in energy networks, HubNet, based on a core of 8 UK universities and a Grand Challenge EPSRC project on infrastructure technologies for the future network, The Transformation of the Top and Tail.
As a research group, we focus on the analysis and technology to support the development of a low carbon electricity supply network that is able to accommodate variable renewable sources and new widespread electric vehicle charging while still delivering a cost effective and very reliable service. My research specialisation is in power electronics for use in power systems. At the high power end of the system this is focused on High-Voltage DC transmission for collection of off-shore wind energy and international inter-connection. In the lower power distribution system, the focus is on managing photovoltaic sources and contributing to voltage regulation. This work is supported by EPSRC, Alstom Grid, National Grid and UK Power Networks
I teach an introductory module in power engineering to Electrical and Electronic Engineering students and specialised modules in later years. Until recently I was also director of undergraduate studies for the department.
