Greg Penner is an Associate Professor and Centennial Enhancement Chair in Nutritional Physiology. He joined the Department of Animal and Poultry Science at the University of Saskatchewan in 2009 after obtaining his BSA (2004) and M.Sc. (2004) degrees from the same University, and his PhD from the University of Alberta (2009). He has developed 2 indwelling pH measurement systems that have been adopted by the research community worldwide. Dr. Penner has a well-funded research program supporting and has trained more than 20 graduate students and postdoctoral fellows. He has published over 90 peer-reviewed papers and provided over 60 invited presentations. Greg also has an active extension program helping to communicate research results to end users and serves as the co-chair for the Saskatchewan Beef and Forage Symposium.
His research program focuses on the development of nutritional strategies to enhance the health and productivity of cattle. This includes fundamental research investigating gastrointestinal physiology with an emphasis on regulatory processes involved in adaptive and recovery responses. Research techniques used within this theme include the use of Ussing chambers as an ex vivo approach and the temporarily isolated washed reticulo-rumen technique as an in vivo approach. Results from the basic research theme are used to develop applied nutritional management strategies to enhance productivity and health of beef cattle, dairy cattle, and sheep.
