Kirsten Meyer

Dr. Kirsten Meyer studies bacterial extracellular vesicles and the delivery of antimicrobials to counter resistance. Kirsten completed a PhD in Pharmacology and Molecular Sciences from Johns Hopkins University as a Fulbright New Zealand fellow, and was a postdoctoral fellow in the Antimicrobial Discovery Center at Northeastern University and in the Nodwell lab at the University of Toronto.

Meyer’s interdisciplinary research bridges biochemistry, microbiology, and pharmacology. Dr. Meyer's research group at the University of Waterloo explores microbial communication and competition to advance novel antimicrobial strategies. Currently they are uncovering the biochemical mechanisms behind the packaging of natural specialized metabolites into extracellular vesicles by Streptomyces bacteria, to enable bioengineering of microbial populations. The group also investigates the antimicrobial properties of these vesicles against problematic microbes and then designs bioinspired lipid nanoparticles for the targeted delivery of cocktails of antimicrobials.
