Biography

Dr. Chris Dent received his BA degree in Mathematics from the University of Cambridge in 1997, and PhD in Theoretical Physics from Loughborough University in 2001. After four years of postdoctorial research in Physics (Heriot-Watt University and Philipps-Universitaet Marburg) he studied for the MSc in Operational Research at the University of Edinburgh in 2005-6. Since the start of 2007 he has worked in energy systems research, first at the University of Edinburgh, and then from 2009 at Durham University where he was appointed Lecturer in Energy System Modelling in 2011 and promoted to Senior Lecturer in 2014. He is also Co-Director for Impact at Durham Energy Institute, an Engineering Mentor at University College Durham, and a senior Research Associate of Peterhouse, Cambridge. His main interests lie in optimisation, resource adequacy assessment, renewables integration, transmission network planning and power system economics, and uncertainty quantification in energy systems models. He has also worked on frequency domain modelling of wave energy converters.

His professional activities being Vice Chair of the IEEE Power and Energy Society Reliability, Risk and Probability Applications Subcommittee and Chair of the PES Working Group on Loss of Load Expectation Best Practices (which shares experience between industrial resource adequacy studies) and the Task Force on Capacity Value of Solar Power. He is an Editor of the Journal of Sustainable Energy Grids and Networks, and on the Editorial Board of the IMechE Journal of Power and Energy for which he recently edited a special issue on renewable energy technologies. In 2014, he was General Chair of the International Conference on Probabilistic Methods Applied to Power Systems in Durham.

In 2012 Dr. Dent received the IET Mike Sargeant Young Engineer Career Achievement Award, and in 2014 he received a Durham University Award for Excellence in Research Impact for on his work with National Grid on the GB Electricity Capacity Assessment Study and with Durham Energy Institute. He is a Chartered Physicist, an Associate Fellow of the Operational Research Society and a Senior Member of the IEEE.
