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.
