His research work focuses on the development of bioprocesses using mammalian cells for the production of recombinant proteins, monoclonal antibodies and viral vaccines. He is particularly interested in the bioprocess conditions that can be used to control the biochemical structure of glycoproteins and hence the quality of biopharmaceuticals. He has always collaborated closely with industry and is a past recipient of the Canadian national Synergy Award for University-Industry innovation. He has been President of the International Society for Protein Expression in Animal Cells (PEACe) and on the editorial board of several journals and major reference works including Encyclopedia of Cell Technology, Biotechnology Advances, Biotechnology and Bioengineering and Comprehensive Biotechnology.
