Research Groups

  • Environmental Dynamics

    Our research focuses on environmental variability throughout the Quaternary and the effects of future climatic change. It is centred on regions especially sensitive to environmental change (tropical, cold and wildfire-prone) and also considers interactions between climate change, human disturbance and catastrophic events.
