Roger is the Director (Interim) of the Monash Energy Institute, Director of Sustainability for Monash Engineering, the Chair of the Australia Photovoltaic Institute and the immediate past President of the Australian Meteorological and Oceanographic Society.  He obtained his BSc (Hons) and PhD at the University of Melbourne, and has worked at the National Center for Atmospheric Research (USA), the Centre Nationale de Recherche Scientifique (France), UNESCO and the International Energy Agency.

Roger began his career working in the field of global carbon cycle dynamics, investigating the processes of carbon exchange between fossil sources, the atmosphere, oceans and terrestrial biosphere.  

A climate scientist by training, his main research focus is on the nexus between weather and climate and the electricity system, looking at how hourly to seasonal variability in wind and solar power can best be mitigated through optimal configuration in time and space, plus the impacts of extreme weather events on energy system infrastructure.  Natural extensions of this are the roles of energy storage and demand-side management such as optimal charging of electric vehicles.
