Description of Research Expertise

My primary research interest lies in understanding how non-clinical social determinants of health as well as organizational and policy variations impact utilization and outcomes in critical illness. I am particularly interested in understanding disparities in ICU utilization and outcomes and hope that my research will lead to clinical and policy efforts to help reduce disparities in critical illness. My thesis has focused on the impact of insurance status on ICU utilization and outcomes using Pennsylvania hospital discharge data. This project found a decreased utilization and increased 30-day mortality for uninsured critically ill patients. I expanded on this research by examining how MA insurance reform impacted critical care utilization and outcomes. I received an F32 individual grant to complete this research and plan to submit a career development award (k08) to further this research.

Description of Clinical Expertise

My clinical practice is focused on Critical Care Medicine, with a primary practice in the Medical Intensive Care Unit at the Hospital of the University of Pennsylvania. Additionally, my practice includes attending on the Procedure and Rapid Response service at the Hospital of the University of Pennsylvania, as well as at the Long Term Acute Care Hospital, at Good Shepard Penn Partners. On the Pulmonary side I am an active preceptor in our Pulmonary fellow's clinic.

Description of Other Expertise

As a resident at Penn, and later as a Botswana-UPenn Partnership faculty member, I worked at Princess Marina Hospital as a specialist physician in Internal Medicine. My primary responsibilities included serving as the attending physician for a team of medical officers from Botswana, as well as supervising the UPenn residents and medical students doing global health rotations on the wards. I continue to be involved with the global health program through my work as a course director for the Low Resource Procedures Course, run at the UPenn simulation center. Students are required to take this course as part of their global health electives. This course grew out of a quality improvement effort and since its inception, blood and body fluid sharps exposures among students have been eliminated.
