Dr. Stewart graduated from the University of Arkansas for Medical Sciences (UAMS) in 1993.  After a transitional internship at UAMS, he completed a stent in the US Army where he served as a clinician in a troop medical clinic and was the chief clinician at a clinic for women’s health.  After this obligation, Dr. Stewart completed an anatomic pathology/clinical pathology residency at the University of Kentucky (UK).  He subsequently completed a cytopathology fellowship at the University of Wisconsin (UW) and a biomedical informatics fellowship at the University of Pittsburgh with an emphasis on pathology education.  He served as a faculty member at UK for a short period before being recruited back to UW.  At UW he worked for a number of years in the Wisconsin State Laboratory of Hygiene and its School of Cytotechnology as the Associate Medical Director.  Dr. Stewart later worked as Associate Director of the cytopathology laboratory and cytopathology fellowship at UW and finally as Medical Director of Watertown Regional Medical Center when it was an adjunct facility of UW.  While at UW, he published some of the first papers on digital imaging in cytopathology education and telecytopathology.  Dr. Stewart eventually went to the University of Minnesota and is the current medical director of the cytopathology laboratory and cytopathology fellowship. 

During his career, Dr. Stewart has served on several national committees for the American Society of Cytopathology (ASC), American Society of Clinical Pathology (ASCP)and College of American Pathology (CAP). He was on the Board of Certification for ASCP on the Cytotechnology exam committee for many years.

Dr. Stewart has always maintained a strong interest in cytology as a screening test for cervical cancer, cytopathology education for cytologists and cytopathologists, and the utilization of imaging as a tool for streamlining cytopathology workflow.
