Research Interests

My research interests are related to decentralised systems (both energy and waste treatment), with a focus on both the technologies, and economic and policy aspects. I undertake research and consultancy at local, UK, EU and international levels. I am active in support of energy policy development, having contributed to the 2003 White Paper analysis on low carbon energy scenarios, the DTI Renewables Innovation Review and preparations for the Prime Minister’s G8 activities on low carbon technologies.


Personal History

I am a Visiting Professor at Imperial, having been a Lecturer/Senior Lecturer/Reader here in the period 1995 to 2007. In September 2007 I moved to the Centre for Environmental Strategy at Surrey University, where I am Professor in Energy and Environmental Systems. I am originally an engineer by first degree, with a bachelors in Mechanical Engineering from Southampton University. I then undertook the MSc in Environmental Technology at Imperial College, followed by a PhD at Imperial in Energy Efficiency and Policy for Central and Eastern Europe.

I am a past Chair of Council of the British Institute of Energy Economics, and immediate past Vice President of the Energy Institute.
