Dr. Xu's research program seeks to optimize the risks and benefits of anticoagulants in the prevention and treatment of arterial and venous thromboembolism among racialized populations, with aims to characterize, understand, and address systemic inequities across the spectrum of thrombosis research and clinical care. His active areas of inquiry include: 

1. Anticoagulant-associated bleeding in racialized populations

2. Racial equity in pregnancy-associated venous thromboembolism

3. Perspectives on thrombosis diagnosis, management and research participation among underrepresented ethnoracial communities
