I am a Postdoctoral Fellow in the Division of Infectious Diseases and the Center for Pediatric Clinical Effectiveness at the Children's Hospital of Philadelphia. I received my PhD in sociology at the University of Pennsylvania. Broadly, my research interests include medical sociology, work and organizations, patient safety, quality improvement and implementation science. I am specifically interested in understanding how the social organization of medical work influences the uptake of standards, guidelines and best practices. Most of my research utilizes qualitative methodology (particularly ethnography) to uncover the mediating conditions that influence whether a practice will be adopted consistently or not. I also enjoy collaborating with clinician-scientists and health policy researchers. I strongly believe that the theories and methodological tools of sociology can be brought to bear fruitfully onto better understanding problems of real-world significance to the health of populations. To date I have examined various case studies of efforts to improve health care quality and patient safety in the United States, including resident duty hour restrictions and infection prevention practices. My current research focuses on the nonclinical factors that shape antibiotic prescribing and the social factors that influence success in antibiotic stewardship. I have received funding from the U.S. Centers for Disease Control and Prevention (CDC), Agency for Healthcare Research and Quality (AHRQ), the Patient-Centered Outcomes Research Institute (PCORI) and the University of Pennsylvania School of Arts and Sciences Graduate Division.
