Dr. Olsen is an associate professor in the Division of Infectious Diseases at Washington University School of Medicine. She received her Ph.D. in microbiology from the University of Pennsylvania and completed a postdoctoral fellowship in clinical and public health microbiology at the University of North Carolina. She is a diplomate of the American Board of Medical Microbiology with subspeciality certification in Virology. Dr. Olsen obtained a master's degree in public health from Saint Louis University in 2001, with concentrations in epidemiology and biostatistics.

Her research interests focus on identification of risk factors and outcomes of healthcare-acquired infections, particularly surgical site infections. She is interested in outcomes of healthcare-acquired infections from the societal and patient perspectives, including clinical outcomes, economic costs, and impact on quality of life. Her work includes the development and validation of computerized methods to perform surveillance for healthcare-acquired infections. She is currently using Medicare and private insurer claims data to identify complications after spine surgery and after mastectomy.

National Cancer Institute, and the Agency for Healthcare Research and Quality.

Dr. Olsen teaches EPI-511, Infectious Diseases Epidemiology, in the School of Public Health. This course provides an overview of the field, including basic microbiology of infectious diseases, methods for surveillance and outbreak investigation, and selected diseases relevant to national or global public health.
