Dr. Buchanan joined SLUCOR in 2005 as a research assistant and became a faculty member in 2009 when she completed her doctorate in Public Health Studies with a concentration in Health Outcomes Research. She has studied the development, progression, treatment and outcomes of chronic and acute illnesses. Much of this work has utilized epidemiological and statistical modeling to examine these relationships in large population-level registries and databases such as those from the VA, Medicare, and national insurance and pharmacy benefit management companies.
Dr. Buchanan is the Operations Manager of SLUCOR’s Consulting Practice. Through the consulting practice she and her team provide methodological and analytic support for many grants and research projects for faculty throughout the School of Medicine, School of Nursing, and College of Health Sciences at Saint Louis University. The support ranges from power and sample size calculations to data analysis and interpretation. Dr. Buchanan has experience with all types for study designs from retrospective to prospective as well as working with sample sizes of 3 subjects to well over a million subjects.
