Research interests

  • My research looks at quantitative genetic variation in farm species, predominantly dairy cattle, but I am also interested in beef cattle and swine. I carry out studies using field-recorded on-farm data (e.g. from Valacta), this involves computer programming and data analyses as well as statistical analyses. Students in my lab need to be interested in computer programming, problem solving, quantitative genetics and statistical analyses, and have a background in, or develop a familiarity with, the agricultural production system relevant to their research area.
  • Associated with my interests in quantitative genetic variation in farm species, I am interested in realised and observed responses to selection in farm species as well as linear model methodology and its application to large data sets.

Potential graduate students

  • I currently have openings for M.Sc. and Ph.D. students, who have scholarships, to work on applied research projects in dairy and beef cattle.

Graduate students
