Roger Cue obtained his PhD in genetics in 1982 (Edinburgh) after completing his undergraduate degree in Agriculture (Newcastle-upon-Tyne, 1978). He joined the department of Animal Science and has served twice as an acting Associate-Dean (Research, and Graduate Education). Since 1999 he has been one of the two representatives of the Dean on the Conseil d’Administration of Valacta (Québec Centre d’expertise en production laitière). He has served as the representative of McGill University on the Conseil d’Administration of the Centre de Développement de Porc du Québec and on the Comité consultatif provincial des bovins de boucherie of MAPAQ. He is particularly interested in the analysis of field-recorded data (e.g. from milk or beef recording schemes) for scientific research and for studies where the results can be directly applied back for on-farm management purposes.
Roger Cue's research looks at quantitative genetic variation in farm species, predominantly dairy cattle, but he is also interested in beef cattle and swine. He carries out studies using field-recorded on-farm data (e.g. from Lactanet), which research involves computer programming and data analyses as well as statistical analyses. Students in the Cue 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 his interests in quantitative genetic variation in farm species, Professor Cue is interested in realised and observed responses to selection in farm species as well as linear model methodology and its application to large data sets.
- Genetic variability in dairy cow profitability;
- Selection intensities and implied economic values in beef and dairy cattle;
- Visualisation of the economic impact of health events in dairy cattle.
