Research Interests

  • The Sterile leucaena project
    Developing breeding and commercialisation strategies to accelerate the availability of sterile leucaena for adoption across the northern beef industry, particularly Western Australian bioregions.
  • Rangeland weed management
    Advance splatter gun technology (low-volume high-concentration herbicide application) for high priority rangeland weeds in northern Australia.
  • Transforming growth pathways with leucaena
    Evaluation of the effect of native trees and low soil sulphur status on the productivity of leucaena grown in lightly timbered basaltic woodlands. The success of these 'lower tier' eucalyptus/leucaena/grass production systems in areas otherwise contained by vegetation management legislation would: (I) increase carrying capacities in north Queensland, (ii) reduce age at turn-off (iii) extend feedbase quality further into the dry-season (iv) enable producers to target premium slaughter markets (v) lift the potential for better rangeland management by reducing stocking rate pressure on native pasture systems, and (vi) contribute to targets for a carbon neutral 2030 beef industry through reduced methane emissions per unit live weight production in up to 7% of the national cattle herd.
