Pseudomonas aeruginosa - a versatile human opportunistic pathogen.


I am currently a tenure-track research fellow at the University of Liverpool, Institute of Infection and Global Health.

My research interests revolve around understanding how pathogens cause disease. My main interests involve the opportunistic pathogen, Pseudomonas aeruginosa, and how it interacts with other species during infection. Deciphering these interactions could be key to both understanding the evolution of successful pathogens and the development of appropriate therapeutics. My research combines genomics, molecular microbiology and population studies combined with relevant infection models.
