Bacterial lifestyles


I am a postdoctoral research scientist working with Cynthia Whitchurch investigating the physiology and molecular mechanisms of regulated cell-wall deficiency as a novel alternative lifestyle in Pseudomonas aeruginosa. I completed my Ph.D. in 2020 in Mark Webber’s group with Procter & Gamble investigating the evolutionary trajectories and collateral selective landscape of antimicrobial resistance in biofilms of P. aeruginosa. Prior to my Ph.D., I completed an MSc in Medical Microbiology with Distinction at the University of Manchester and a BSc in Biology.
