About this doctor:

Dr. Oh specializes in general thoracic surgery, which includes benign and malignant diseases of the lung, pleura, esophagus, mediastinum, and chest wall. He has an interest in applying and expanding the role of minimally invasive and robotic technology in the diagnosis and treatment of the conditions afflicting his patients. Recognizing some of the limitations of standard thoracoscopic surgery or VATS (Video Assisted Thoracoscopic Surgery), he currently utilizes robotic technology with the da Vinci system to perform surgery when appropriate. These techniques allow for operations to be performed through small incisions for less pain and a shorter recovery period.

Dr. Oh is also an integral part of the multidisciplinary USC/Norris Lung Cancer Program, one of the few programs in the country where patients with lung cancer can be evaluated simultaneously in one visit by physicians of different specialties, such as thoracic surgery, pulmonary medicine, medical oncology, and radiation oncology. This unique team approach allows patients to benefit from real time multidisciplinary discussion of their care to provide the most advanced and personalized care possible in a streamlined setting.

Dr. Oh obtained his surgical training at two internationally recognized institutions for thoracic surgery – USC and Harvard Medical School. He has gained extensive experience in the full spectrum of thoracic surgery, including minimally invasive lung resection, minimally invasive esophageal surgery, advanced endoscopic and bronchoscopy technology, and the treatment of uncommon thoracic malignancies such as mesothelioma.

Dr. Oh’s primary research interest is to apply the genetic information of thoracic tumors to personalize patient therapy. His prior research has shown that even early stage tumors have distinct genetic signatures that can identify patients at risk for recurrence. Ultimately this approach is hoped to “fingerprint” tumors to assess their potential for metastatic spread following resection.  His research has been presented at several international meetings and published in numerous professional journals.
