Arnaud Guittat, a Researcher with RPA, has a degree in Industrial Risk Management and Impacts on the Environment from an engineering school called INSA de Rouen (National Institute of Applied Sciences) in his native land of France. He also spent half a year of his undergraduate degree at the Norwegian University of Science and Technology in Trondheim (Norway). Since joining RPA in early 2008, he has been involved in a variety of projects covering risk analyses, impacts assessments and cost-benefit analyses. Recent projects have included the modelling of future demand and supply of mercury in the UK and the assessment of risks related to wind turbines. He has played a vital role in elaborating socio economic analyses by developing statistical and mathematical models used in deriving cost and benefit estimates..
