Biography

Dr. Keith Youker earned his Ph.D. in Cardiovascular Sciences from Baylor College of Medicine and was the first graduate from this program. The program initially used a broad knowledge approach to training including course work from medical school, graduate school, and cardiovascular core courses designed for basic scientists to work in clinical cardiovascular research. His dissertation work earned him a nomination for the Sigma Xi “Excellence in Science Dissertation Award”. Since graduation, Dr. Youker has been a faculty member in both the departments of Medicine and Surgery at Baylor College of Medicine prior to joining Houston Methodist Hospital. He has served as an ad hoc reviewer for the journals of Circulation, American Journal of Pathology, ASAIO and the Journal of Heart and Lung Transplantation. Dr. Youker’s primary focus has been in heart failure with a particular interest in inflammation and its role in the progression of heart failure. Dr. Youker prefers a hands-on approach in the laboratory and is expert in many areas from electron microscopy to molecular biology techniques and has earned a reputation of excellence in cardiovascular immunopathology research.

Description of Research

Dr. Youker focuses on research of the immune system in heart failure and metabolism in heart failure.
