Why Drylands?

Drylands are critical regions of the globe where water and nutrients are greatly limited. These marginal environments can undergo significant ecosystem transformations associated with land degradation which may persist for hundreds to thousands of years with important consequences for the sustainability of water and land resources. Drylands and their resources are currently under immense pressure from climate change, periods of drought, anthropogenic activities and conflict and thus present multiple environmental and societal challenges of global significance.

What we do

Our group works on various processes in dryland environments ranging from theoretical questions to applied problems. Our research covers:

  • runoff generation
  • hillslope and channel sediment transport
  • hillslope-channel coupling
  • drainage basin evolution
  • stochastic rainstorm simulation
  • climate change impacts
  • biogeochemical cycles
  • dryland ecosystem degradation (desertification)
  • dryland soil metagenomics
  • impacts of war and conflict on dryland ecosystems

Methodologically, we develop and apply numerical models, carry out field data collection, use various analytical laboratory methods, and conduct physical experiments. A bit of everything!
