Primary Research Interest

The Berti Lab investigates how combining antibiotics in a deliberate and rational manner can improve outcomes for patients with challenging bacterial infections. We integrate pharmacokinetics, bacteriology, molecular biology, metabolism and recombinant genetics to examine when combination therapy is appropriate, why combination therapy can provide benefit and how best to administer antibiotic combinations.

  • Mechanisms of Antimicrobial Resistance
  • Mechanisms of Antimicrobial Tolerance
  • Optimization of Pharmacological Interventions
  • Staphylococcus aureus
