Dr. Kerry LaPlante’s Pharm.D. clinical practice site and research program is located at the Veterans Affairs Medical Center in Providence, R.I., and the College of Pharmacy at URI. She is nationally recognized for her work in the treatment, virulence inhibition, control and prevention of methicillin-resistant Staphylococcus aureus (MRSA) and device related infections where she has authored more than 100 peer-reviewed journal articles, abstracts and textbook chapters. Since her independent research career began in 2004 she has securing uninterrupted funding from the National Institutes of Health (NIH), Veterans Health Agency, and several investigator initiated grants from the Pharmaceutical Industry. Her research has been presented throughout Europe and the United States.

Her research program has recently expanded to include an antimicrobial research outcomes component, which focuses on Antimicrobial Stewardship and Comparative Effectiveness Research using the National Veterans Affairs Database databases and statewide initiatives.

Dr. LaPlante also serves the profession by membership, leadership and participation in a number of Infectious Disease organizations, and serves as the infectious diseases section editor for the journal, Pharmacotherapy. She is also an active reviewer for Antimicrobial Agents and Chemotherapy, Clinical Infectious Diseases, The Journal of Antimicrobial Chemotherapy, and Diagnostic Microbiology and Infectious Diseases. Dr. LaPlante is a member and leader of many professional societies and taskforces within pharmacy and infectious disease groups and serves as an expert consultant for several pharmaceutical and device related companies.


Dr. LaPlante’s foremost research expertise is in the treatment, outcomes,prevention, virulence inhibition (biofilm and toxin), and decolonization of multiply drug resistant bacteria, specifically Methicillin resistant Staphylococcus aureus (MRSA).
