Research interest


My research topics focus on studying bacterial physiology, pathogenesis, and antibiotic response.
Antibiotic resistance is a major health problem. However, even without resistance, many infections are hard to treat and tend to relapse. Even without increase in the minimal inhibitory concentrations, cells can survive longer even in presence of lethal concentrations of bactericidal antibiotics. In the lab, we use different in vitro and in vivo approaches  to understand why bacteria that are sensitive to antibiotic survive. We focus on Escherichia coli, a commensal, opportunistic pathogen and a major cause of urinary tract infections. We are working towards  deciphering mechanisms of antibiotic survival in commensal and pathogenic extraintestinal E. coli strains using physiologically relevant conditions.
