Dr. Dowell completed his medical school education at the University of Chicago and received his internal medicine training at UT Southwestern. He then pursued his fellowship in Hematology and Oncology at Vanderbilt University, where he received extensive mentorship in thoracic malignancies from leaders in that field. Following fellowship, given his affinity for the clinical, research, and teaching environment at UT Southwestern, Dr. Dowell returned to join the faculty. Dr. Dowell specializes primarily in thoracic malignancies, including but not limited to non-small cell and small cell lung cancers, mesothelioma, and thymoma. He is also an active investigator in the clinical research program for these cancers at UT Southwestern. Dr. Dowell's approach is to educate patients and their families about their illness so that they can make informed treatment decisions. In addition, Dr. Dowell is devoted to medical education.
In 2018, he was named a Super Doctor by Texas Monthly.
His interests outside of work include travel, baseball, and family activities.
