Feeding the growing world population in a dynamically changing environment is one of the great challenges of the future!
From studying roots to their growing environments, we try to discover how root-microorganism dynamics can be optimized with genetics or management to save water, land and fertilizer in agricultural and natural systems.

Plants obtain water and mineral nutrients through their roots, and thus roots sustain global biomass productivity. However, studying roots comes with challenges from their complex physiology and their soil and whole-plant environments.
This is further complicated due to the presence of myriad of microbial species where roots survive in the hidden zone of soil. Research in the Watt Group focuses on discovering how root-microbe interactions can be improved for increased biomass.

Dr Suzanne Donn
Dr Suzanne Donn is investigating how plants and their root associated bacteria respond to soil warming, including interactions between wheat cultivars and the base climate scenario. Suzanne completed her PhD at the Scottish Crop Research Institute (now the James Hutton Institute), linking changes in nematode community structure to barley crop management strategies and comparing taxonomic identification to DNA based methods. Following this, …

Dr Sneha Gupta
Dr Sneha Gupta is a Postdoc working in close collaboration with Michelle Watt and Prof Ute Roessner. She uses the microcosms, called ‘EcoFAB’ to test the effects of plants on the N movement from soil to plant without and with inhibitors (including the commercial inhibitors NBPT and DMPP) in Australian soils. Sneha just finished her PhD under Prof Ute Roessner working on soil …

Lisa Mau
Lisa Mau is a graduate researcher in the Jülich-University of Melbourne Postgraduate Academy (JUMPA) with UoM and the Forschungszentrum Jülich (FZJ) in Germany. Lisa’s PhD project brings together unicellular algae with wheat roots. Algal biomass contains nutrients, but unlike mineral fertilizer, in chemical forms that are not directly available to plants. She is using a mass-balance model to calculate phosphorus release by …
