Johannes R. Kratz, M.D. is Director of Minimally Invasive and Robotic Thoracic Surgery and holds the Van Auken Endowed Chair in Thoracic Oncology. Kratz graduated magna cum laude from Harvard Medical School and holds a Masters in Philosophy from Stanford. 

Kratz worked as research fellow in the Thoracic Oncology Lab from 2008-2011 where he played a pivotal role in the development of a prognostic assay for early-stage lung cancer patients. The novel assay was validated in an international clinical trial led by thoracic surgeons David M. Jablons, M.D. and Michael Mann, M.D. The assay better predicted risk of death in early-stage lung cancer patients versus conventional staging guidelines and later successfully identified Stage 1A lung cancer patients who had a very high likelihood of mortality after surgery. Kratz finished his clinical training as a clinical fellow in Thoracic Surgery at UCSF from 2014 - 2017.

Kratz has published numerous papers and has been the recipient of numerous awards and honors including the Partners Healthcare Resident/Fellow as Teacher Award, Willard M. Daggett Award, Edward Churchill Surgical Research Fellowship, Wyeth Scholarship of the American College of Surgeons, John E. Thayer Scholarship Award, Howard Hughes Medical Fellows Program Continued Support Award, Howard Hughes Medical Student Research Fellowship, and designation as a Soma Weiss Scholar.

Kratz was recently honored with the 2017 UCSF Health Exceptional Physician Award for service during the last year of his clinical fellowship, among 8 winners out of 61 nominees, notably the only clinical fellow at UCSF to receive the award in 2017, and one of only two winners not on the faculty.

The Kratz lab focuses on the genetic and immunological mechanisms that drive early-stage, surgically resectable thoracic malignancies. These malignancies include lung cancer, esophageal cancer, and thymic cancer. The lab uses novel high-throughput "-omics" techniques such as genomic DNA and RNA sequencing, proteomics, and metabolomics to unravel the complex nature of early-stage thoracic malignancies. At the same time, the lab actively investigates the complex immunological landscapes that nurture the growth of these malignancies. The knowledge gained from these investigations is being used to identify novel therapeutic targets and therapies for patients with early-stage, yet deadly thoracic malignancies.
