Rate My Professor Dena Lyras

Lyras's research specializes in the pathogenesis of enteric bacterial pathogens, particularly Clostridioides difficile, examining host-pathogen interactions, toxin secretion, sporulation processes, antibiotic resistance, and lateral gene transfer in antibiotic-associated diarrhoea. Her laboratory employs genetic tools, animal infection models, and translational studies to develop immunotherapeutics and small molecules as non-antibiotic treatment strategies in collaboration with industry partners. She has authored 171 papers, accumulating more than 11,250 citations. Key publications include "A Clostridioides difficile endolysin modulates toxin secretion without cell lysis" (2024, Communications Biology), "Mechanisms of blaIMP-4 dissemination across diverse carbapenem-resistant clinical isolates" (2025, Journal of Global Antimicrobial Resistance), "A widespread hydrogenase supports fermentative growth of gut bacteria in healthy people" (2025, Nature Microbiology), and "Microbes as architects of colonic patterning" (2026, Cell Host & Microbe). Notable awards include the Australian Research Council Laureate Fellowship (2021, the first for an academic woman in her faculty), BacPath Oration Award (2022), Australian Society for Microbiology Distinguished Orator Award (2023), and election as Fellow of the American Academy of Microbiology.
