Dr. Zachary Armstrong, a native of Iqaluit, Nunavut, obtained his B.Sc. — majoring in chemistry and biochemistry — from the University of British Columbia. His final year project, performed under the guidance of Professor Steve Withers, focused on the creation of a GH11 thioglycoligase [1]. He completed his PhD at the University of British Columbia, co-supervised by Professors Steven Withers and Stephen J. Hallam. This work focused on the identification of glycoside hydrolases from metagenomic sources — including the beaver gut[2],a mining bioreactor[3] and soils[4]— and the engineering of glycosynthases from a metagenomes and synthetic gene libraries (ref). In 2018 he joined the group of Gideon Davies in the York Structural Biology Laboratories at the University of York as a postdoctoral research associate. His current work focuses on mechanism-based inhibitors and activity-based protein profiling of human carbohydrate processing enzymes.
He has determined the crystal structure of :
