Associate Professor John Church
Position: Cattle Research Chair
Affiliation: Natural Resource Science
InterestsFatty acid and related nutritional composition of beef
Life cycle assessment and empirical measurement of greenhouse gas emissions from beef production
Beef cattle welfare and optimization of beef cattle production
Research InterestsIn July 2008, Dr. Church accepted the new position as the B.C. Regional Innovation Chair in Cattle Industry Sustainability at Thompson Rivers University. The Chair leads a multidisciplinary research team dedicated to the exploration and invention of innovative practices and technologies leading to the sustainability and enhancement of the cattle industry, rangelands, and meat production and related products. The scope encompasses production of the grazing animals through to harvesting, raw and value added meat products, and the preservation of the natural resources on which these industries depend. Studies include policy, economics and business aspects for each of these sectors. The objective is to catapult the meat and rangeland industries from their current status to successful Trade Mark Industries for British Columbia.
EducationDr. Church earned his PhD in Agriculture, Food and Nutritional Science from the University of Alberta in 1997, studying the effects of production practices on the behaviour of ruminant animals. He holds a M. Sc in Biology from Dalhousie University in Nova Scotia (1993), and a B. Sc. in Agriculture from the University of Alberta (1991).

Employment HistoryDr. John Church is an experienced researcher and ranch manager with seven years of experience with the Alberta provincial government and five years of work experience in the livestock industry. ). Prior to joining Alberta government, John was employed in the private sector for five years, as an animal behaviour consultant to the oil and gas industry, working primarily with elk and bison, and as a manager of a large ranching operation in southern Alberta where he actively raised many diverse species such as bison, elk, white-tailed deer and caribou and beef cattle. While managing an extensive ranching operation that was uniquely vertically integrated, Dr. Church was able to learn first hand the benefits of value chains within that industry, and the importance of environmental sustainability.
