His research focus was on creating thinner skin flaps for reconstruction and on tendon healing. After completing his research fellowship and general surgical training, he received his plastic surgery training at Massachusetts General Hospital. Following this, he did an additional six-month fellowship at Brigham and Women's Hospital, also in Boston. The focus of this fellowship was on complex microsurgical reconstruction of the breast, hand, and lower extremity.
