Biography/ Background

Background

2014 – present, Senior Lecturer, University of Adelaide. I am a Postgraduate Coordinator for the School of Agriculture, Food and Wine.

July 2010 – 2013, Lecturer, University of Adelaide. I am a Postgraduate Coordinator for the School of Agriculture, Food and Wine.

2006-2010 Senior Research Scientist, DPI Victoria, managing the Victorian node of the National Rhizobium Program, in collaboration with colleagues at the Centre for Rhizobium Studies, SARDI, DEEDI and NSW I&I, and the CRC Future Farm Industries project 'Acid tolerant lucerne rhizobia' with SARDI and NSW I&I researchers.

2002-2006 ARC Postdoctoral Scientist and Lecturer, at the University of Western Australia, School of Plant Biology, investigating the phosphorus nutrition of native species, including native legumes with potential as pasture species.

2000-2002 Postdoctoral Scientist, University of Minnesota, USA, Department of Agronomy and Plant Genetics, researching legume physiology.

For further details, see:

My research interests are in crop and pasture agronomy, with a strong focus on the role of legumes in farming systems particularly in their contributions of nitrogen supply through N fixation. Research has included assessment of inoculation technologies, analysis of nodulation and nodule occupancy using molecular techniques, and the measurement of nitrogen fixation, principally through isotopic techniques. Other research has investigated phosphorus acquisition mechanisms (carboxylates, phosphatases, root biology) in legumes and other plant groups. New projects have a focus on N cycling in farming systems and in conservation cropping.

Research Funding

ARC Industrial Transformation Research Hub 2015-2019, Legumes for Sustainable Agriculture

This 5-year project will focus on improvements to chickpea N fixation and abiotic constraints. In collaboration with USyd (major partner), SARDI, UWA, ANU, Flinders Uni.

 

Intensifying crop / livestock systems in Laos and Cambodia (scoping study), 2014, ACIAR

This project identified some key issues related to intensification of crop / livestock systems in Lao PDR and Cambodia and identified a pathway for the development of a new project, flagged for 2016-2019.

 

Nitrogen Fixation Program – southern region 2012-2017, GRDC

Pulse and pasture legumes can provide an abundant, inexpensive and sustainable source of N into Australian cropping systems. This project will improve the amount of fixed nitrogen (N) contributed to cropping systems in southern Australia (South Australia, Victoria and southern NSW) from pulse legumes.

Collaborators: Dr Liz Drew and Mr Ross Ballard, SARDI; USyd, DAFWA, Centre for Rhizobium Studies, DEEDI

 

Extension of Nitrogen Fixation Program – southern region 2012-2017, GRDC

This project will work in coordination with other groups around Australia including the Centre for Rhizobium Studies, DAFWA and DEEDI to deliver accurate, relevant, up-to-date information to key growers and agricultural consultants.

Collaborators: Dr Maarten Ryder, Univ Adelaide; Mr Ross Ballard, SARDI; USyd, DAFWA, Centre for Rhizobium Studies, DEEDI

 

Evaluation of the field efficacy of beneficial microbial products 2012-2013, GRDC

Beneficial microbes include bacteria and fungi which may have improve growth by suppression of plant disease or through plant root growth stimulation.This project will evaluate the field efficacy of multiple putatively beneficial organisms.

 

Development of conservation cropping systems in the drylands of northern Iraq 2012-2015, ACIAR

This project will improve the productivity and profitability of crops in the drylands of northern Iraq through the application of conservation cropping technologies involving zero-tillage (ZT), stubble mulching, improved crop cultivars and better crop management. Long-term benefits of conservation cropping include improved soil structure and reduced soil erosion.

Collaborators: Dr Yi Zhou and Prof David Coventry, University of Adelaide, Dr Stephen Loss, Dr Colin Piggin, ICARDA (Syria/Jordan), University of Mosul (Iraq), Ministry of Agriculture (Iraq), Prof Kadambot Siddique, University of Western Australia, Dr Jack Desbiolles, UniSA, Dr Jim Fortune, Rural Solutions.

 

Increasing productivity of legume-based farming systems in the Central Dry Zone of Myanmar 2013-2017, ACIAR

The farming communities in Myanmar are poor, with many families spending 70% of their income on food. Providing small-holder farmers with new technologies (crops, varieties and inoculants etc) to increase agricultural productivity through collaborative RD&E is an effective option to address the issues of poverty alleviation and food security.

Collaborators: Prof David Herridge, Dr Chris Guppy, Mr Craig Birchall, University of New England (Australia), Department of Agricultural Research (Myanmar), Yezin Agricultural University (Myanmar), ICRISAT (India).
