Zachary Willis, MD, MPH

Director, Pediatric Antimicrobial Stewardship Program Assistant Professor, Pediatric Infectious Disease

Dr. Willis is a specialist in pediatric infectious disease with particular interest in studying antibacterial resistance and promoting antimicrobial stewardship. Antimicrobial overuse is prevalent in human and veterinary medicine, and complications can include adverse drug events, Clostridium difficile infection, and subsequent infection with antimicrobial-resistant organisms. In particular, his research focuses on educating medical professionals about appropriate use of antimicrobials for children in outpatient and inpatient settings. This includes prescribing, preparing, administering and monitoring use of antimicrobials through quality improvement measures as well as developing effective, low-cost strategies to address antimicrobial misuse. Dr. Willis is also studying antibacterial resistant infections and associated complications, as well as antibiotic overprescribing trends in common pediatric conditions, like acute otitis media.
