Vineyard Engineering and Technology
Grapevine Ecophysiology and Climate Change
- Hydraulic and chemical signaling in grapevines under water stress and recovery
- Mitigation of heat stress in grapevines using mister-based cooling
- Deficit irrigation strategies to reduce night transpiration and improve grapevine water use efficiency
- Understanding the effects of temperature on grape volatiles
Advanced Sensing Technologies in Vineyards
- Biotic and abiotic stress detection in grapevines using proximal and remote sensing techniques
- Plant sensor-based precision irrigation in vineyards
- Thermal infrared sensing of plant water stress
- Using in situ microtensiometers for continuous stem water potential measurements
- Collaboration with UWS Hawkesbury Institute for the Environment Link
I am currently accepting post-graduate (Ph.D.) students who have a background in either viticulture, biological or agricultural sciences or engineering, and who are interested in working in the following research areas:
- Environmental stress physiology of grapevines, particularly heat and drought stresses
- Modeling multiscale and multiphase water transport in grapevines
- Environmental factors affecting flavour and aroma compounds in winegrapes
- Application of proximal and remote sensing techniques in vineyards to quantify vine physiological performance and yield
