Volker Krey

Volker Krey graduated in theoretical physics from the University of Dortmund (Germany) in 2002. In 2003 he joined the Institute of Energy Research - Systems Analysis and Technology Evaluation (IEF-STE) of the Research Centre Julich, where he continued to work until 2007. Since 2006 he has held a PhD in mechanical engineering from the Ruhr-University of Bochum (Germany). Dr. Krey first visited IIASA as a participant of the Young Scientists Summer Program in 2004. He joined IIASA's Energy Program in October 2007 and since October 2011 is the Deputy Program Leader.

Dr. Krey’s main fields of scientific interest are the integrated assessment of climate change and the energy challenges, including energy security and energy access. His work focuses on the development and application of integrated assessment models with different regional focuses (national to global scale) and time horizons. In addition, decision making under uncertainty, in particular in the context of future energy transitions and climate change mitigation strategies has been an important part of Dr. Krey's research activities.

He has been appointed a Lead Author of the recently published IPCC Special Report on Renewable Energy Sources and Climate Change Mitigation, a Lead Author of the Global Energy Assessment (GEA), and a Lead Author of the IPCC 5th Assessment Report. Since 2010 he is an Associate Deputy Editor of the well-known journal Climatic Change. Dr. Krey also teaches in an MSc program on "Renewable Energy in Central and Eastern Europe" at the Vienna University of Technology (Austria).
