Research interests

  • Analysis using splines of repeated measures data coming from pasture trials
  • Comparing methods to determine cooking time of chickpeas


Steven joined the then Department of Agriculture and Fisheries (NSW DPI) in December 1989. He was employed as a biometrician’s assistant and then as a Technical Officer until 2001 when he obtained his current position as a Biometrician at the Tamworth Agricultural Institute (TAI). Work at Tamworth involves collaborating with researchers at TAI as well as at Narrabri, Armidale and Glen Innes. The researchers at these sites are involved in pastures research, meat science, soil science, entomology, chickpea quality and breeding programs. DPI’s in-house software “DIGGER” is used to produce efficient experimental designs for early generation selecting of chickpeas and durum wheat varieties.
