Current Project

NamTip - Understanding and managing desertification tipping points – a Namibian perspective

I am currently a postdoctoral researcher within the NamTip project. My work mainly focuses on detecting desertification tipping point with the help of our climate and grazing manipulation field experiment called TipEx.


Research Interests

  • Global change ecology
  • Vegetation response to drought and disturbance
  • Ecosystem resilience
  • Ecosystem tipping points and regime shifts
