My role in the department

I conduct machinery research on broadscale crops, such as improving seeders, sprayers and harvesters. I am keen on showing growers the benefits of a controlled traffic farming system. Preserving the soil properties for maximum crop production is hard without controlled traffic as modern machinery is getting much heavier. I believe autonomous vehicles have huge potential in agriculture to reduce dangerous, boring, repetitive or skilled labour shortages.

My background

I have more than 30 years experience in agricultural research on cereal and pulse crops in Western Australia. I am originally from a black soil farm near Toowoomba Qld where I completed my Ag. Engineering degree. Then I moved to the USA for a masters degree in Ag. Engineering and finally in Merredin for farm machinery research. Currently I am the national chair of the Society for Engineering in Agriculture of Engineers Australia.
