My role in the department

I have been leading a GRDC funded project ‘Evaluating herbicide tolerance of new crop varieties in Western Region with National Coordination’ since 2000. This project aims to increase farm profitability by matching herbicides to varieties of cereals, lupins, pulses and canola. It is a nationally co-rodinated project and impacts crop protection at the national level.

In addition, I also work on herbicide options for effective weed management in quinoa, a new crop to Australia.

My background

I have over 20 years experience in weed research and extension including herbicide crop tolerance, herbicide resistance, herbicide efficacy, crop-weed competition, weed biology and crop phenology. I have largely worked in rainfed cropping systems in Western Australia but spent my first five years of research work at the Punjab Agricultural University working in irrigated systems. I also regularly act as external examiner of honours, MSc and PhD theses from various national and international universities and a reviewer of several scientific research journals.
