Johannes Kratz

MD

Thoracic and cancer surgeon
Director, Advanced Minimally Invasive Thoracic Surgery
Early-stage lung cancer researcher, avid skier and biker

Dr. Johannes Kratz is a thoracic surgeon who specializes in treating disorders of the trachea, chest wall, lung, esophagus and mediastinum (the space between the lungs containing the heart and other structures). He directs UCSF's program for advanced minimally invasive thoracic surgery.

Kratz's research interests include robotic surgery outcomes, lung and esophageal cancers, biomarkers to personalize lung cancer treatment and immunotherapies for thoracic tumors. His current research focuses on understanding the molecular and genetic profiles of high-risk tumors in early stages and developing targeted therapies to treat them.

While a surgical research fellow at the UCSF Thoracic Oncology Laboratory, Kratz developed a test that more accurately predicts outcomes for patients with early-stage lung cancer. Now available to patients, this test has improved outcomes for those with high-risk lung cancer detected early.

Kratz earned his medical degree at Harvard Medical School, graduating magna cum laude. He completed a general surgery residency at Massachusetts General Hospital, followed by a fellowship in cardiothoracic surgery at UCSF. He also has a master's degree in philosophy from Stanford University.

Kratz is a member of the American College of Surgeons, Society of Thoracic Surgeons, Massachusetts Medical Society and American Society of Clinical Oncology. In 2017, he received a UCSF Health Exceptional Physician Award. He is the Van Auken Endowed Chair in Thoracic Oncology at UCSF.

    About our process

    As usual I had more questions after the visit. I found his option of a more conservative approach a possible game changer to other diagnoses I had received. I appreciated the fact that questions I submitted on MyChart were responded to that same day.

    I would recommend Dr. Johannes Kratz to anyone I know going through a similar illness, he has been the first provider to listen to my concerns and make a plan of action to take care of it. It was so easy to schedule for my procedure and I am so happy with this process.

    Dr Kratz has an awesome bedside manner, is very knowledgeable and really helped to explain things and settle my nerves. Looking forward to PET scan and possibly surgical removal of lung mass.
