Senior Research Scientist


I joined the Lewis lab in 2011 after completion of my PhD in University College Dublin under Dr. Jim O’Gara, which was focused on Staphylococcal biofilm formation. During my PhD, I identified the protein Aap as a mediator of the primary attachment phase of biofilm formation in S. epidermidis. I also worked on the role of teichoic acids in S. epidermidis biofilm formation. My current research interests include Staphylococcus aureus persister cell formation, biofilm tolerance to antimicrobials and methods to eradicate persisters.
During my time in the Lewis lab, I have been, and continue to be involved in seminal studies on novel antibiotic treatments for S. aureus infection. I led a project on acyldepsipeptides (ADEPs) killing persisters, which was published in Nature in 2013. I continue to work on ADEPs and their capacity to eradicate various bacterial populations. I was involved in the characterization of teixobactin, a new antibiotic produced by a previously uncultured soil bacterium. This work was published in Nature in 2015. I continue to investigate the novel mechanism of killing of teixobactin. I am also committed to identifying the mechanism by which S. aureus persisters evade the bactericidal action of antibiotics and have made major advances toward this goal.
My major goal is to continue to discover novel mechanisms to target and kill S. aureus and I believe this will lead to greatly improved treatments of chronic and complicated Staphylococcal infections.
