Dr. Berry practices all aspects of thoracic surgery, including procedures for benign and malignant conditions of the lung, esophagus, and mediastinum. He has a particular interest in minimally invasive techniques, and has extensive experience in treating thoracic surgical conditions using video-assisted thoracoscopic surgical (VATS), laparoscopic, robotic, endoscopic, and bronchoscopic approaches. He serves as the co-Director of the Stanford Minimally Invasive Thoracic Surgery Center (SMITS), and has both directed and taught in several minimally invasive thoracic surgery courses.

Dr. Berry's clinical research activities mirror his clinical interests and activities in optimizing short-term and long-term outcomes of patients with thoracic surgical conditions. He has more than sixty peer-reviewed publications, most of which are related to both the use of minimally invasive thoracic surgical techniques as well as evaluating outcomes after treatment of thoracic malignancies. His clinical practice and his research both focus on choosing the most appropriate treatment and approach for patients based on the individual characteristics of the patient and their disease process.
