Research focus

  My research focuses mainly on:

  • Climate-vegetation interaction/feedback,
  • Climate extremes and land-use change impacts,
  • Global/regional climate/land surface modelling,
  • Land-based climate change mitigation,
  • Weather extreme attribution and uncertainties assessment
