I study various aspects of plant morphology and ecophysiology: water uptake of crop plants, desert species and temperate trees under salinity and drought, root architecture and physiology, and root system plasticity under intra- and inter-specific competition. I maintain my interests in plant carbon metabolism under salinity and drought, with an emphasis on root turnover, respiration, and exudation, and develop advanced approaches and methodologies which could enhance belowground studies. A long-term goal of my research is to provide a better understanding of the fundamental mechanisms which determine how root system architecture and physiology respond to environmental constraints to optimise the (carbon-)efficiency of resource use. I am developing scientific instrumentation with various partner organisations, using on demand production chains such as 3D printing.Please visit www.rootecology.de and www.vienna-scientific.com for further information.
