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 healthcare utilization and outcomes and hope that my research will lead to clinical and policy efforts to help reduce disparities in critical illness. My masters in clinial epidemiology 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 with an F32 NIH grant to examine how MA insurance reform impacted critical care utilization and outcomes.

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, I provide critical care, as well as pulmonary consultation at the Philadelphia VA Medical Center. My outpatient pulmonary practice at the Philadelphia VA Medical Center includes expertise in tele-health.

In addition I am a consult at the Bucks County Health Department in Tuberculosis.

Description of Other Expertise

I am a course director of Doctoring IC, a second year medical student course on professionalism, and serve on the leadership committee for Module 6.

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.
