Research Abstract
As a physician-scientist and a pediatric infectious diseases specialist, I am committed to maximizing the efficacy of our current antimicrobial options and developing host-directed therapeutics to overcome antimicrobial resistance and improve treatment outcomes for patients. With this framework in mind, my laboratory examines:
(A) Drugs that directly boost the antibacterial killing capacity of host phagocytic cells;
(B) Drug repurposing for difficult to treat bacterial infections;
(C) Novel antimicrobial susceptibility testing paradigms for drug-resistant bacterial pathogens.
