Doctor Markus Nolf

Markus NolfDr Markus Nolf joined the Hawkesbury Institute for the Environment as a Post-Doctoral Fellow in the Plants, Animals and Interactions theme in May 2015. He is currently working with Dr Brendan Choat on an ARC Future Fellowship project titled "Limits to the resilience of Australian forests and woodlands to drought", which centres on mapping the vulnerability of trees to drought across Australian biomes.

Dr Nolf obtained his PhD at the Institute of Botany, University of Innsbruck, in 2015 under the supervision of Prof. Stefan Mayr. His PhD research in plant hydraulics was centred on the coordination of hydraulic parameters in trees, shrubs, and herbaceous species. Studies were based on classical hydraulic measurements as well as non-destructive methods, in the laboratory and under field conditions ranging from tropical lowland rainforest to the alpine timberline.

Dr Nolf's main research interests revolve around plant water relations in terrestrial plants, with a focus on the water transport system. Specific interests include the vulnerability and adaptation of plants to drought, the trade-off between hydraulic efficiency and safety, and recovery of hydraulic function after periods of stress. He has investigated temporal and spatial patterns of embolism formation during drought and freezing using classical destructive as well as novel, non-invasive techniques such as acoustic emission analysis and electrical resistivity tomography.
