Research Summary

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, Hellman Family Clinical-Translational Research Development Award, Howard Hughes Medical Student Research Fellowship, Michael DeBakey Research Scholarship, and designation as a Soma Weiss Scholar.
