Researcher biography

Dr Auzmendi

In my PhD I analysed and modelled biophysical processes (light interception, transpiration and photosynthesis) and their relationships in apple and pear trees during the growing season and at different levels of plant water status. During this time I collaborated in the upgrade of a functional-structural peach model (L-PEACH). Later I focused my research on the effect of carbohydrates on grapevine and berry growth, as well as the effects of light, temperature and VPD on carbon assimilation and transpiration both at leaf and canopy level.

Currently, I am undertaking research on improving management practices in avocado, macadamia and mango. I am focused on studying architecture, vegetative vigour, crop load and light interception using functional-structural plant modelling to understand the interactions between management practices, environmental factors, plant carbon balance and growth.
