Dr. Barker completed his Internal Medicine residency training at Northwestern Memorial Hospital in Chicago, Illinois in 2010.  He served there an additional year as a teaching hospitalist, supervising inpatient internal medicine teams of residents and medical students where he received a teaching award.  He subsequently joined the faculty at UT Southwestern in the Department of Medicine in the fall of 2011.  He maintains a busy general internal medicine primary care practice and also frequently supervises inpatient teaching teams at both Parkland Memorial Hospital and Clements University Hospital throughout the year.  In addition to patient care, he quickly identified a passion for medical education and became Co-Director of the Internal Medicine Clerkship in 2014.  He was honored to be selected as a Graduation Marshal by the UT Southwestern Medical School graduating class of 2016.  He then transitioned to Associate Dean of Student affairs in 2017 where he is thrilled to be part of team that supports the development of the next generation of physicians.
