Research Interests

  • Physiological plant response on future climate conditions
  • long and short-term stress response
  • primary and secondary plant metabolism
  • Sink-Source-Interactions: Plant performance when environmental stress on photosynthetically activ organs is increasing and carbon/water dynamics are limiting sink supply
  • Combined heat- and drought as trigger for stress response in Aleppo Pine (pinus halepensis)
  • Tools: simulation of future climate conditions in greenhouse growth chambers
  • gas exchange measurements - CO2 , H2O, BVOC
  • central carbon metabolism measurements
  • ROS metabolism measurements



  • CliFF: Climate feedbacks and benefits of semi-arid forests,funded by German Research Foundation (DFG)


CliFF Cooperations

  • Weizmann Institute of Israel, Department of Earth and Planetary Sciences
  • Dan Yakir`s Lab, Eco-Physiology Group
