His interest in physiology and biomedical research began in 1977 when he was recruited to participate as a subject in a study on lactic acid and distance running performance.{{Cite journal |last=Farrell |first=P.

Formative mentors and collaborators include professors Eddie Coyle, Jack Wilmore, John Holloszy, Douglas Stuart, Doug Seals, Roger Enoka, Jim Hagberg, Marlys Witte, Jerry Dempsey, Kai Rehder, and John Shepherd.{{Cite journal |last=Joyner |first=Michael J. |date=May 2015 |title=Mentorship and Learning to Ignore |url=https://pubmed.ncbi.nlm.nih.gov/26390711 |journal=The Physiologist |volume=58 |issue=3 |pages=115, 125–126 |issn=0031-9376 |pmid=26390711}}

Joyner is currently the Frank R. and Shari Caywood Professor of Anesthesiology at the Mayo Clinic, where his laboratory has been funded continuously by the National Institutes of Health since 1993.{{Cite web |url=http://www.the-aps.org/mm/Education/Continuing-Education/Professional-AwardsFellowships/Teaching-Mentoring-Awards/Schmidt-Nielsen-Award/Awardees/Past-Award-Recipients/Michael-J-Joyner-MD |title=Michael J.
