Dr Ehsan Tavakkoli

BScAgr, MScAgr (UNE), PhD (The University of Adelaide)

Dr Tavakkoli is trained as an environmental soil scientist and crop physiologist. His research covers various aspects of soil-plant interactions, biogeochemistry, contaminant risk assessment and characterisation of soil solution chemistry. Dr Tavakkoli is responsible for the Soil Research laboratories in Wagga Wagga Agricultural Institute, where work in soil chemistry, physics and crop nutrition is undertaken. Before joining NSW DPI he worked at the University of Southern Queensland, University of South Australia and at the University of Adelaide (Waite Research Institute) where he developed research on limitations to yield in saline-sodic soils, beneficial use of coal seam gas associated water, functional characterisation of contaminant-nanoparticle associations and increasing carbon storage in alkaline sodic soils. He has also been involved in the development of various approaches that employ synchrotron techniques in soils which allow highly spatially-resolved in situ analyses to be performed.

Dr Tavakkoli is developing his research in the field of soil chemistry and plant nutrition because of the need for fundamental and applied research of interactions between soil-water-plant using novel and multidisciplinary approaches. Since most soils suffer from one or more nutritional problems (deficiency and/or toxicity), this subject is of considerable importance for two of the great challenges confronting humanity: how to sustainably support over 7 billion people (increasing to around 9 billion in 2050), and how to deal with global environmental change.
