Dr. Collier is a former Animal Sciences Department head who has had a distinguished career in the field of dairy sciences. Prior to joining the University of Arizona in 1999, he worked as a professor of dairy science at the University of Florida and was also the Dairy Research Director for the Monsanto Company. Currently Dr. Collier teaches undergraduate courses and conducts research in the fields of environmental physiology with a focus on the dairy industry.
The focus of this laboratory is in studying environmental effects on gene expression in domestic animals. Research program utilizes both practical management models as well as controlled environmental facilities to modify environments around animals. Environmental effects on gene expression are then evaluated using gene expression microarrays, real time PCR and northern blots. Domestic animals of interest include dairy and beef cattle, horses, sheep and goats.
