I completed my PhD at the Department of Plant Sciences, University of Graz, Austria, in March 2008 after studying the ecophysiology of light use and antioxidative defence in Pinus radiata. I sought to identify (1) how light use and antioxidative defence are affected by nitrogen fertiliser application and (2) if there are differences in light use and antioxidative defence among genotypes. Since April 2008, I am investigating drought stress responses of Allocasuarina luehmannii (buloke), an endangered woodland tree. I am addressing my research questions from a biochemical, physiological and whole-plant scale.
