    • Assistant Clinical Professor:
      • Touro University, College of Pharmacy
      • UC Davis, School of Medicine

    Education:

    PharmD., Touro University, Mare Island, 2010

    PGY2 Infectious Diseases Residency, UC Davis Medical Center, 2011-2012

    Research Interests

    New agents: antimicrobials and antifungals, antimicrobial dosing in critically ill, improving antimicrobial stewardship services, Outpatient Parenteral Antimicrobial Therapy (OPAT), and reducing C. difficile infections.

    Practice Philosophy

    I am an antimicrobial advisor. My goal is to create customized therapy plans for each patient based on a multitude of factors. Understand that each patient is different from the neonate to someone’s great-grandmother, the gymnast from the linebacker. The world of ID is fascinating and not only is the patient and the drug involved critical to consider in therapy decisions, but we must also consider the “bug” where did it come from, is it resistant, and can we reach it with our therapy.

    Rotations Precepted

    Infectious Diseases Consult (PGY1 and PGY2)

    Antimicrobial Stewardship (PGY1 and PGY2)

    Infectious Diseases Pediatric Consult (PGY2)

    Additional PGY2 ID rotations precepted, please see PGY2 in Infectious Diseases Link
