Dr. Ngadi is a Fellow of the Canadian Society for Bioengineering. He earned his doctoral degree from Dalhousie University (formerly TUNS) in Halifax, Nova Scotia. He previously worked with Laval University, Quebec and University of Georgia, Georgia before joining Â鶹Çø in 1998. He is a professional member of the Canadian Society for Bioengineering (CSBE), American Society of Agricultural and Biological Engineers (ASABE) and Institute of Food Technologists (IFT).
Dr. Ngadi’s research interest is to understand how product and process inter-relate and translate to optimized food quality and safety. The emphasis of his work is on mathematical modelling and optimization, heat and mass transfer phenomena, food properties, hyperspectral imaging, deep-fat frying and cooking processes, bulk packaging and non-thermal technologies including pulsed electric fields (PEF), ultraviolet light (UV), and ozone. Dr. Ngadi also works on biofuels and bioproducts. The major thrust of his research in this regard is on enhanced biochemical conversion of waste biomass into biofuels as well developing innovation strategies for conversion of biomass into bioproducts. His work has resulted to over 200 publications and reports of inventions. He has supervised over 30 graduate and postdoctoral students.

Research Interests
Dr. Ngadi works on improving the way food products are manufactured in order to ensure their optimal quality and safety. To do this, he develops new techniques of applying conventional processing technologies or he deploys novel and emerging non-thermal technologies such as pulsed electric fields (PEF), ultrasound, ultraviolet light (UV), and ozone to produce food products that are safe and of high quality. He studies the properties and attributes of foods in order to assess their states during various process operations. Dr. Ngadi uses non-destructive methods such as computer imaging and spectral methods to facilitate rapid and online assessment of food quality and safety of products. He also applies mathematical modelling to effectively characterize and optimize processing operations.
Dr. Ngadi also works on biochemical conversion of food processing waste materials into biofuels and functional bioproducts.
