Personal profile

Biography

Daniel started work at UWA in 1999 after spending 4 years conducting agricultural research in the UK. He currently manages a research program that addresses issues relating to the development of sustainable management practices for agriculture, horticulture and mine sites under rehabilitation. The biological fertility of soil is a major focus of this research where staff and students employ a range of molecular, isotopic, biochemical and enzymatic tools to study microbial ecology and nutrient cycling and issues relating to microbial function and diversity. Research is primarily funded through the Australian Grains Research and Development Corporation, the Department of Agriculture Fisheries and Forestry, the Australian Research Council and industry partners.

Roles and responsibilities

Development of equipment to measure gross N fluxes in coarse textured soils.
Established soil organic matter fractionation protocol for WA soils.

Previous positions

1998 – 1999 Research Scientist
IACR-ROTHAMSTED
Soil Science Department, Harpenden, Hertfordshire, AL5 2JQ, U.K.

The focus of this research was to use isotopic pool dilution techniques to further develop a process-based understanding of nutrient cycling in agricultural, grassland and natural systems. The ratio of gross nitrification to ammonium immobilisation was assessed as an index of N loss against modelled and measured leaching rates. The same principles were also used to assess the concept of ‘N saturation’ across a European N deposition gradient. Research also addressed the movement and loss of dissolved organic matter.

1995 – 1998 Postdoctoral Research Scientist
IACR-ROTHAMSTED
Soil Science Department, Harpenden, Hertfordshire, AL5 2JQ, U.K.

My contract was a joint appointment between Rothamsted and the Institute of Grassland and Environmental Research (IGER). Overall focus of this research was to develop detailed data sets on nutrient cycling and soil organic matter for model development (mechanistic; based on turnover of soil organic matter fractions) and evaluation (SUNDIAL/Roth-C).

Collaborators: Dr Steve Jarvis and Dr David Hatch (IGER), Dr Decland Barraclough (Reading University), Dr Mark Shepherd (ADAS)
