Research Summary:

The focus of Dr. Walker’s research is a patient focused approach to optimization of antimicrobial use in hospitalized patients. Her initiatives typically evolve from questions that arise from clinical practice in infectious diseases and antimicrobial stewardship at Sunnybrook.

Dr. Walker’s patient-focused research initiatives encompass work in the following areas: antimicrobial use (selection, adverse events and drug interactions), patient outcomes, screening tools for infection, antimicrobial pharmacokinetics, dose optimization based on pharmacokinetic and pharmacodynamic principles, antibiotic resistance, antimicrobial stewardship and pharmacy practice.
