Biography

Steve leads AGBU R & D in breeding objectives and selection indexes for beef cattle. A key development of his work is the BreedObject technology, which focusses BREEDPLAN genetic evaluation on selection. In addition to influencing developments in other species, applications of the technology extend across all major beef breeds and internationally.

Steve's interests encompass the genetics of each of the major trait areas of animal production. His early career included research in meat science and sheep breeding. In addition to his own research, he has had important design responsibilities for major industry programs including for the Cooperative Research Centre for Beef Genetic Technologies, and from 2007 to 2009 was also Associate Editor (Animal Genetics) of Journal of Animal Science for the American Society of Animal Science.

Qualifications

  • PhD (Ohio State)
  • MScAg (UNE Armidale)
  • BScAgr (Hons) (Sydney)

Research Interests

Steve leads the R&D in breeding objectives and selection indexes for beef cattle. A key development of his work is the BreedObject technology. His main research intersects the following:

  • Breeding objectives and multiple trait selection
  • Genetics and environment interrelationships
  • Selection for non-additive merit
  • Genetic and phenotypic prediction
  • Economics in animal breeding
  • Experiment design and analysis
  • A key development of his work is the BreedObject technology.

Current Projects

  • Selection to reduce methane while improving productivity
  • Selection to improve feed efficiency jointly with other traits
  • Individual animal-level assessment of trait importance
  • Environment-level effects on genetic parameters
  • Incorporating DNA markers in multiple trait selection
  • Accuracies for multiple-trait selection indexes
  • BreedObject software system development
  • Genetics of tropically adapted and 50% tropically adapted cattle
  • Genetics of maternal traits
