Mike Duffey

Dr. Mike Duffey is a faculty member in the Department of Kinesiology at Pennsylvania State University and Biomechanist for the Golf Teaching & Research Center (GTRC).

Mike completed his Master’s in Exercise Science at Wake Forest University; his thesis examined how lower body 3D kinematics and ground reaction forces influence running injuries.

He completed his PhD in Biomechanics at Penn State where his research focused on upper body kinematics and muscle activity during resistance exercise.

In 2006, Dr. Duffey returned to Penn State University as a faculty member in the Department of Kinesiology and began collaborating with the Professional Golf Management Program.

That collaboration has led to the development of the Golf Teaching and Research Center.

Dr. Duffey’s roles in the GTRC include detailed swing assessment, instructor education, and conducting research.

The research focus of the center is to develop a better understanding of the mechanics of the golf swing with the goals of improving performance at all playing levels as well as reducing the injury in golf.
