Research Vision:

Clinical outcomes in adult cardiac surgery focusing on mechanical circulatory support and ventricular assist devices. Importantly, mentoring residents who are interested in a career in cardiac surgery is a major component of my research.

Research Areas:

• Ventricular assist devices

• Heart transplantation

• ECMO
