Supervision Statement

  • I am available for supervision of PhD, Masters by Research, Masters by coursework (Projects A and B) and Honours students.

    Projects that I supervise are in nitrogen management in agriculture from fertilisers, wastes and recycling systems. I have expertise in soil nitrogen transformations, use of enhanced efficiency fertilisers, gaseous emissions, and use of stable isotope tracing techniques, and both laboratory and field based projects are available.
    Current projects relate to N use efficiency in high rainfall and irrigated dairy systems (field and laboratory), capture and recycling of N from animal wastes streams (dairy, laboratory and field), nutrient release from fertilisers, nitrification and urease inhibitors.

    Current PhD students;
    Microbially mediated nitrogen conservation and loss pathways in low and high N input rice paddies (A. Pandey)
    Composting lignite amended cattle manure: understanding the biochemical and physical changes, nutrient release and impacts on soil health and plant yield (R. Impraim)
    Effects of urease and nitrification inhibitors on soil microbial communities and nitrogen use efficiency (A. Lucibia)
    Life cycle assessment of greenhouse gas (GHG) emissions from beef production systems and the development of nitrogen footprint credentials of beef products in Australia (T. Li)

    Recently completed PhD students;

    Impacts of a nitrification inhibitor on nitrogen cycling pathways and associated functional microorganisms in Australian agricultural soils (X. Shi, 2017)
    Efficiency of ammonium sulphate as a source of nitrogen and sulphur in wheat and canola cropping systems in south- eastern Australia (M. Khan, 2017)
    The effect of soil and environmental variables on N2 O leakage from nitrification (R. Liu, 2015)
    Enhancing Nitrogen Fertiliser Efficiency
