Dr. Predicala manages the Engineering Research Program at PSCI with the following goals: to address environmental sustainability issues associated with swine production and to optimize the physical environment in swine production facilities to enhance performance and reduce production cost. For the past 7 years, Dr. Predicala has secured more than C$1.7 million in extramural research funding for individual and collaborative projects mainly aimed to ensure health and safety of barn workers and pigs, control environmental emissions, and comply with applicable environmental and occupational regulations. During this period, he has supervised and coordinated the work of a team of Post-doctoral Fellows (2), Research Assistants (4), Research Technicians (3), Graduate Students (3 Ph.D. students, 4 M.Sc. students), and Undergraduate Student Assistants (4) in the implementation of project workplans. Dr. Predicala also holds concurrent appointment as Adjunct Professor at the Department of Chemical and Biological Engineering at the University of Saskatchewan. He is also actively engaged with professional societies, currently serving as an officer of the Canadian Society for Bioengineering, as member of various committees of the American Society of Agricultural and Biological Engineers, and as Associate Editor and reviewer for professional journals.
