While at the MSU College of Human Medicine he spent two years at the Flint MI MSU Clinical Campus and two months living abroad in Peru, completeing the school's MD Leadership in Medicine for the Underserved certificate program.  He completed his residency training in Emergency Medicine at the Oakland University William Beaumont School of Medicine's / William Beaumont Hospital Emergency Medicine Program, where he served as Chief Resident in his final year.  

Upon completing residency in 2019, Dr. Harrison entered a two year Fellowship in Clinical Research, studying heart failure and cardiovascular imaging under the mentorship of Dr. Phillip Levy at Wayne State University.  He concurrently entered the Clinical Research Design and Statistical Analysis MSc program for clinician-scientists at the University of Michigan's Department of Biostatistics.  He graduated both his research fellowship and his MSc in 2021, at which time he took his first full time faculty position as a tenure-track Assistant Professor of Emergency Medicine at IUSM in Indianapolis.  

Dr. Harrison works clinically at IUH Methodist Hospital, while continuing the translational and health services research he began during his fellowship, in acute heart failure and non-invasive cardiovascular imaging.  Starting in 2022, and ending in 2024, he recieved a KL2 Career Development Award funded by the National Institutes of Health National Center for Advancing Translational Sciences (NIH NCATS) through the Indiana Clinical and Translational Sciences Institute.

As of 2023 he has been married for 10 years to his wife Ashley, an adult primary care nurse practitioner. They have two children, Abigail and Hannah.
