Dr. Gregory Freisinger, Ph.D.

Associate Professor

Dynamics Systems Thread Leader


Dr. Greg Freisinger is a 2006 graduate of the Georgia Institute of Technology, where he majored in Mechanical Engineering and was an Army ROTC cadet. He commissioned as an Engineer Officer and was assigned to the 84th Engineer Battalion in Schofield Barracks, Hawaii. He deployed to Thailand on a humanitarian construction mission as a platoon leader and later to Iraq as Executive Officer of the Forward Support Company. Greg left active duty in 2010, where he enrolled at The Ohio State University eventually earning a MS and PhD in Mechanical Engineering with a focus on orthopaedic biomechanics. Dr. Freisinger has taught dynamics, vibrations engineering, and biomechanical engineering while advising many varied capstone and independent study projects. He is also assigned as an Innovation Officer with the 75th Innovation Command as a US Army Reservist and a Class of 2014 Tillman Scholar. 

Ongoing Research Projects

Co-investigator of Measuring and Assessing Soldier Tactical Readiness and Effectiveness, DARPAs Measuring Biological Aptitude, and Thermoregulation in Veterans with Spinal Cord Injury.
