Joel T. Weadge graduated with his B.Sc. from the University of Guelph in 2000 and then went on to do his Ph.D. in Microbiology at the same institution under the tutelage of Professor Anthony Clarke. Following completion of his Ph.D. in 2006, Dr. Weadge then undertook a research fellowship appointment (2007-2008) with Dr. Monica Palcic in the enzymology research group at Carlsberg Laboratory in Copenhagen, Denmark. He then joined Dr. Lynne Howell’s lab as a postdoctoral fellow (2008-2011) in the Molecular Structure and Function program at the Hospital for Sick Children in Toronto.

Joel Weadge is an Associate Professor in the Biology Department at Wilfrid Laurier University. Dr. Weadge graduated with his B.Sc. from the University of Guelph and then went on to do his Ph.D. in Molecular and Cell Biology at the same institution under Dr. Anthony Clarke while studying peptidoglycan acetylesterases. Dr. Weadge then undertook a research fellowship appointment with Dr. Monica Palcic in the enzymology research group at Carlsberg Laboratory in Copenhagen, Denmark, where he worked on structure-function relationships of glycosyltransferases, including those responsible for blood group determination. He then joined Dr. Lynne Howell’s lab as a postdoctoral fellow at the Hospital for Sick Children in Toronto with CIHR and NSERC fellowships. While at Sick Kids, he continued to work on glycosyltransferases and acetyltransferases inherent in the alginate biosynthetic complex. Dr. Weadge’s diverse research experiences in the structure-function characterization of glyco-enzymes and protein export apparati from a variety of carbohydrate systems (peptidoglycan, alginate, blood group antigens) form the basis for his group’s current research interests on cellulose, an exopolysaccharide found in bacterial biofilms.
