Julio Diaz Caballero

Postdoctoral Researcher in Microbial Genomics, University of Oxford

I am a researcher focused in understanding how bacteria evolve within their hosts. Specifically, I am interested in how intraspecific bacterial populations evolve to overcome challenges in their environment, e.g. antibiotic therapy. I use genomics, bioinformatics and statistical methods to identify differences between bacteria and use these differences to create a biography of infections. My goal is to leverage the knowledge of how bacterial populations evolve to improve therapies targeting life-threatening infections. My research and training has taken me from Peru -> USA -> Canada, and I am now in the UK as part of a team that studies within-host Pseudomonas aeruginosa infections in Intensive Care Unit patients across Europe at a high-resolution.
