Research description

Dr. Jayas is a former Tier I (Senior) Canada Research Chair in Stored-Grain Ecosystems. He conducts research related to drying, handling and storing of grains and oilseeds and digital image processing for grading and processing operations in the Agri-Food industry. He has collaborated with researchers in several countries and has had significant impact on the development of efficient grain storage, handling and drying systems in Canada, China, India, Ukraine and the United States. He has authored or co-authored nearly 1000 technical articles in scientific journals, conference proceedings and books dealing with issues of storing, drying, handling and quality monitoring of grains.

Distinguished Professor Dr. Digvir S. Jayas was educated at the G.B. Pant University of Agriculture and Technology in Pantnagar, India; the University of Manitoba; and the University of Saskatchewan. He has recently completed his term as Vice-President (Research and International) at the University of Manitoba. Before assuming the position of Vice-President (Research and International), he was Vice-President (Research) for two years, and Associate Vice-President (Research) for eight years. Prior to this, he was Associate Dean (Research) in the Faculty of Agricultural and Food Sciences, Head of the Department of Biosystems Engineering, and Interim Director of the Richardson Centre for Functional Foods and Nutraceuticals. For a year, he has served as Interim President of Natural Sciences and Engineering Council of Canada (NSERC) and 4.5 months he served as Interim Director (CEO) of TRIUMF-Canada’s particle accelerator centre. He is a Registered Professional Engineer and a Registered Professional Agrologist.
