My Files

I am an ecologist, who comes from a conservation background, and have worked with both flora and invertebrates. My current research is to try and gain insight into how the physical environment influences plants, and what this means for pathogenic manifestations. There is a need for in-depth knowledge of specific environmental conditions that allow trees to either grow more vigorously, or show stress, and then to relate the observed pest and pathogen communities to this gradient. Understanding the ecological basis of plant-herbivore patterns would complement existing research in alleviating current tree die-back problems in either plantation forestry, or native forests.
