He also led the creation of three new, two-year clinical campuses in Traverse City, Midland, and Southfield near Detroit. 

The majority of Dr. Sousa’s work is in medical education and curriculum. He led the design of the college’s new and highly successful Shared Discovery Curriculum, which is characterized by robust clinical experiences in each year of medical school, promotion based on progress testing, and content organized by chief complaint rather than organ system or discipline.

As the leader of the college’s $30 million expansion in Flint, Dr. Sousa was the PI on the C.S.

The division has reached nearly $60 million in federal funding since starting in late 2014.

Dr. Sousa is a practicing general internist. He received his bachelor’s in chemistry and his medical degree from Indiana University. He then served as both a resident and chief resident in internal medicine and completed a Primary Care Fellowship at Michigan State University.
