Research interest
microbiology, antibiotic resistance, virulence.
My work is on multidrug-resistant plasmids in Enterobacterales. I investigate the response of recipient bacteria to the acquisition of these plasmids, and the impact on the spread of antibiotic resistance and bacterial virulence in E. coli.
