Jennifer E. Earl, Ph.D., A.T.C. 

Assistant Professor 

Interests and Expertise
Etiology and rehabilitation of lower extremity athletic injury. Specific interests include lower extremity functional alignment and poor neuromuscular control as contributing factors to patellofemoral pain and ACL injury. Ongoing studies include examining the role of the gluteus medius in controlling lower extremity motion, and the development of rehabilitation exercises to improve the neuromuscular control of the hip during physical activity.
