Dr. Predicala manages the Engineering Research Program at PSCI, with an overall goal of improving air quality inside hog barns to reduce odour and gaseous emissions to the environment, and developing housing and management systems that optimize pig welfare and productivity. He obtained his Ph.D. from Kansas State University and his M.Eng. degree from Asian Institute of Technology in Bangkok, Thailand. Dr. Predicala is also an Adjunct Professor in the Department of Agricultural and Bioresource Engineering, University of Saskatchewan.

Education

• Ph.D., Kansas State University, 2003
• M.Eng., Asian Institute of Technology, 1995

Current Research Program

• Development and evaluation of engineering control measures to reduce risk of worker exposure to hydrogen sulphide (H₂S).
• Evaluation of applicability of a biological treatment approach in controlling H₂S generation from swine manure.
• Novel application of nanoparticles to reduce odor and gaseous emissions from swine operations.
• Assessing the impact of swine sulphur intake from drinking water on emissions and on manure nutrients.
• Reducing energy costs in swine barns to enhance the competitiveness of the pork industry.
