  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
