He has also led quality improvement initiatives aimed at optimizing chemotherapy delivery workflows to reduce treatment delays and hospital length of stay. Complementing this education-focused work, his peer-reviewed scholarship has included investigations into biomarker utilization and health care resource use, disparities in cardiovascular outcomes, viral pathogenesis and clinical outcomes in solid and hematologic malignancies, reflecting a broader interest in applying rigorous clinical research methods to improve care delivery and trainee education across disciplines.
