Dr. Sunil Singhal is a General Thoracic Surgeon and practices surgery on all aspects of the chest.  His practice is focused on lung cancer and esophageal cancer, including complex resections and advanced disease.  He performs minimally invasive (VATS and robotic) pulmonary surgery.  In addition, he performs mediastinal surgery (diseases of the thymus gland), pleural disease, microinvasive hyperhidrosis surgery and pectus excavatum (Ravitch and Nuss repairs).

Dr. Singhal is the Director of the Thoracic Surgery Research Laboratory and his interest lie in intraoperative imaging to detect small quantities of disease and immunotherapy to treat patients with advanced lung and thymic cancer.  He is conducting several clinical trials to improve care for patients with advanced disease for cure.
