As an infectious diseases clinical pharmacist, Dr. Ramanathan’s research interests encompass areas related to infectious diseases pharmacotherapy and antimicrobial stewardship. Dr. Ramanathan employs various antimicrobial stewardship interventions to help optimize clinical outcomes, while minimizing unintended consequences of antimicrobial use, including toxicity, the selection of pathogenic organisms, and the emergence of resistance. Her research has primarily focused on the use of procalcitonin and data-mining tools, such as Pharmacovigilanz, to promote being better stewards of our limited antimicrobial resources.
