Dr. Abbott received his PhD from the University of Victoria in 2005. He then studied the molecular basis of protein-carbohydrate interactions under Dr. Alisdair Boraston at the University of Victoria. In 2008, Dr. Abbott joined Dr. Harry Gilbert's group at the Complex Carbohydrate Research Centre, at the University of Georgia where he investigated the functional genomics of carbohydrate utilization pathways from intestinal bacteria. Currently, Dr. Abbott is a Research Scientist for AAFC based at the Lethbridge Research Centre and Adjunct Professor at the University of Lethbridge. His research program investigates the mechanisms of complex carbohydrate modification by intestinal bacteria, and is developing applications for carbohydrates in animal agriculture and human intestinal health. See Abbott Group and Abbott Google Scholar for more information on research activities.
