About Dr. Chen
Qiudong (Kevin) Chen is a clinical fellow in cardiac surgery. He completed his general surgery training at Cedars-Sinai Medical Center in Los Angeles, California, where he served as the administrative chief resident in his final year. During residency, he also completed a two-year NIH T32-sponsored research fellowship in cardiac surgery, focusing on comparative outcomes research using large clinical and administrative registries in the areas of heart and lung transplantation, mechanical circulatory support, and valvular heart disease. He hopes to pursue an academic career in cardiac surgery after training.
