Biography

Dr. Ochoa Arenas received his medical degree in his native country of Colombia. He completed a research doctorate and a postdoctoral fellowship (both focused in lung endothelial biology) under Troy Stevens at the University of South Alabama and Charles Hales at Harvard University.  Following this, Dr. Ochoa Arenas was then accepted into the highly competitive Physician-Scientist Training Program here at UT Southwestern Medical Center where he trained in internal, pulmonary, and critical care medicine as well as tumor stromal biology under Dr. Lance Terada.  Currently, Dr. Ochoa Arenas divides his time between his research laboratory and Parkland Memorial Hospital.  Dr. Ochoa is passionate about serving the Parkland population as well as working closely with the residents and fellows in the medical intensive care unit and the lung diagnostics clinic.  Dr. Ochoa Arenas is a medical officer in the U.S. Air Force Reserve.

His interests outside of Medicine include CrossFit and visiting state and national parks.
