Key Research Interests and Expertise

 

  • Policy relevant science related to climate change and sustainability
  • Integrated assessment modelling of climate change, climate change mitigation and adaptation, and sustainability in the context of the goals of the Paris Agreement to limit global warming to well below 2C above pre-industrial levels

 

  • Linkages between land use change policy and climate change policy; exploring the land-water-energy nexus in relation to climate change, agriculture and ecosystem conservation

 

  • Quantification of the benefits of climate policy and climate change mitigation, in particular the avoided climate change impacts 

 

  • Climate change impacts on ecosystems and species, and hence ecosystem services and the economy

 

  • Robustness of integrated assessment results to uncertainties within and between models

 

  • Making policy relevant science available and useful to policy makers, stakeholders and the academic community.
