Research Interests

My primary research interests involve the epidemiology of hospital-acquired infections, particularly surgical site infection, and the use of administrative and claims data to study surgical complications. I am interested in identifying operation-specific risk factors and developing risk prediction models for surgical site infections after specific procedures (particularly spine and breast cancer surgery). My other active area of research involves the development of methods for electronic and claims data-based surveillance to determine the incidence and outcomes of surgical site and other hospital-acquired infections. I am very interested in determining outcomes of hospital-acquired infections from both the societal and patient perspective, including economic costs and impact on quality of life.
