Jason DeFreitas

Professor
Department Chair

Jason DeFreitas (he/him/his) joined the Department of Exercise Science in the Falk College of Sport and Human Dynamics in the Fall 2024 semester as a professor and department chair.

Prior to joining Syracuse University, DeFreitas was an associate professor and program coordinator of the Health and Human Performance program at Oklahoma State University. He spent 11 years at Oklahoma State, where he primarily taught classes in neuroanatomy and neuromuscular physiology.

DeFreitas’ research focuses on how the brain controls movement, and how that control system changes with aging and/or training. His lab utilizes brain stimulation techniques, functional brain imaging, nerve conduction studies, and more. He has a strong applied focus with goals of reducing fall risk in older adults through physical activity interventions and improved diagnostic testing.

His lab, the Neural Health Research Laboratory, is currently supported by the De Luca Foundation and the American Federation for Aging Research (AFAR) Award in Aging Biology and Geroscience Research, a three-year award sponsored by the Hevolution Foundation.

While at Oklahoma State, Dr. DeFreitas won multiple university-wide research awards, including the President’s Fellows Faculty Research Award (2021), the Distinguished Early Career Faculty Award (2019) and the Regents Distinguished Research Award (2018). He also won multiple university-level awards for his graduate student mentorship, including the Phoenix Award (2015) and Advising Excellence Award (2015).

DeFreitas earned a Ph.D. in 2013 and master’s degree in 2009, both from the University of Oklahoma. He received his bachelor’s degree in 2007 from the University of Connecticut.
