Biographical Details
Dr Guppy trained as a soil chemist at the University of Queensland before taking up an academic position at the University of New England in 2003. His main research areas are soil phosphorus chemistry, root responses to nutrients, rhizosphere chemistry and silicon dynamics in soils. The interaction of nutrient supply and root response is currently investigated using state-of-the-art micro-CT tomography. UNE has a strong focus on farming systems research and he has consequently been involved in a number of large farming systems research programs funded by GRDC and MLA. Dr Guppy has published over a 100 peer-reviewed journal articles in soil and plant fertility and is an Editor with Plant and Soil. He has also supervised nearly 50 postgraduate students to completion in 20 years and finds that amongst the most rewarding aspects of the position.
