He has also been involved in building a range of models, including the UK MARKAL model, and the UK TIMES model. Prior to joining UCL, Steve gained extensive international energy modelling experience. Between 2009 and 2012, he worked on a range of large scale projects for USAID in the Balkan region, Asian Development Bank (ADB) in Pakistan and US DOE in the USA. All projects have focused on MARKAL/TIMES model development and analysis of long term sustainable energy pathways, with strong capacity building aspects.
