Welcome to the McGregor Research Group web site. We are part of the pharmacoepidemiology research core in the Oregon State University College of Pharmacy. Our research aims to improve antibiotic utilization to optimize patient care and limit the spread of antibiotic resistance. Our work includes a strong focus on antibiotic use in outpatient settings and on the quality of patient care during transitions between healthcare settings. We are located in Portland, Oregon on the College of Pharmacy’s campus at Oregon Health & Science University.
