After receiving his Bachelor of Science in chemistry from Indiana University and his Master of Science in computer science and physiology from Purdue University and Indiana University, respectively, Dr. Stephens received his Doctor of Medicine from the Indiana University School of Medicine in Indianapolis.

He completed a radiology residency at University of Louisville in Louisville, Ky., followed by a cardiothoracic radiology fellowship at the National Jewish Health/University of Colorado at Denver.

Dr. Stephens is certified by the American Board of Radiology.

He has contributed to several journal articles and abstracts on topics including distinguishing malignant and benign lung nodules utilizing standardized per nodular parenchymal features from CT; the identification of nonaggressive pulmonary nodules using an optimized scoring system; and infraspinatus suprascapular nerve branch compression.

In addition, Dr. Stephens contributed to a book chapter on the identification of biological relationships from text documents as well as an online publication about developing laboratory information management, analysis, and bioinformatics solutions for microarrays.

Dr. Stephens also presented at a Radiological Society of North America (RSNA) conference on how evaluating characteristics of intrapulmonary lymph nodes could change the management of pulmonary nodules.
