Research Overview
Dr. Olsen’s background is in clinical microbiology, epidemiology and biostatistics. Her primary appointment is in the Division of Infectious Diseases. Dr. Olsen’s primary interests include the epidemiology of hospital-acquired infections, particularly surgical site infections after breast cancer and spine surgery. More recently, she has become interested in using large administrative and claims datasets to study infectious and noninfectious complications of surgical procedures. The claims data offer advantages to these studies because of the large numbers of surgical procedures and infectious outcomes, and generalizability due to inclusion of procedures performed at multiple hospitals or ambulatory settings. Use of claims data for secondary analysis also entails many challenges, and Dr. Olsen is working to develop algorithms for researchers using these data to study complications after events (such as surgical procedures).

Dr. Olsen teaches a course in Infectious Disease Epidemiology in the Saint Louis University School of Public Health MPH program.
