Today’s interview is with Dr. Josh Hagen, the director of the Human Performance Collaborative at Ohio State University and an Associate Research Professor in the university’s Department of Integrated Systems Engineering.
Joining co-host Ken Ford for this episode is IHMC’s Chief Strategic Partnership Officer Morley Stone who has a long history with Josh has and been instrumental in his career.
Today we talk with Josh about his work at the Human Performance Collaborate, which brings together multi-disciplinary teams of researchers, sports scientists, data scientists, and practitioners with the goal of optimizing human performance in Ohio State athletes.
Within the human performance research area, Josh leads two areas: Sport and Tactical Performance Science and Recovery Science. At Ohio State, Josh works with other performance-science researchers to evaluate the physical traits and capabilities of athletes. Josh and his colleagues then collaborate with coaches and athletic trainers to make adjustments in the weight room, on the field, and during recovery after training or competitions.
In addition to his work at Ohio State, Josh also is working on federally funded projects in human performance with Special Operations Command, The Air Force Research Laboratory, the Office of Naval Research and several private foundations. Josh joined IHMC in 2022 in a collaborate role as a Visiting Senior Research Scientist.
Josh is a graduate of the University of Cincinnati where he studied and earned a Ph.D. in materials science and engineering. He spent 11 years at the Air Force Research Laboratory, which is where Morley and Josh first worked together. After his stint at the Air Force Research Laboratory, Josh headed for West Virginia University as the director of the Human Performance Innovation Center at the Rockefeller Neuroscience Institute before moving to the Ohio State University.
