People

Lori Michener, PhD, PT, ATC, SCS, FAPTA

Principal Investigator


Dr. Michener’s research characterizes the biomechanics of musculoskeletal shoulder pain, diagnosis and treatment of shoulder and cervical pain, clinical trials investigating optimal treatment strategies for shoulder and cervical disorders, and the use of patient-rated outcomes measurement tools to assess health related quality of life. She is the Director of the COOR (Clinical biomechanics and Orthopedic Outcomes Research) Laboratory. As the Director of Clinical Outcomes and Research, she directs the development, collection, and analysis of patient-rated outcomes and the process of care in the USC Physical Therapy Associates Clinics, and serves as a resource for clinical research.

Jonathan Sum, PT, DPT

Clinical Faculty Associate
2015-Present

Dr. Sum specializes in treating patients with orthopedic disorders, sports-related injuries, post-surgical rehabilitation, pain management and musical performance-related injuries. He is double board certified in both orthopedic and sports physical therapy and is an executive board member of the American Society of Shoulder and Elbow Therapists (ASSET). His research is focused on understanding physical factors related to the development of shoulder and elbow pain and its impact on baseball pitching, throwing, and hitting performance, as well as characterizing physical factors related to the evaluation and treatment of shoulder pain.

Adam Barrack MS, CSCS, TSAC-F

Doctoral Student
2020-Present

Adam completed his Master of Science degree in Biokinesiology at the University of Southern California under co-advisors Dr. Lori Michener and Dr. Chris Powers. Excessive shoulder and elbow torque is associated with the prevalence of upper extremity injuries in baseball players. While pitching is a total body action, little is known about the role of the lower extremity in development of torque at the upper extremity. His current work will build upon his interest in joint and segmental contributions to complex motion by describing lower extremity kinematics and kinetics during the baseball pitch, and defining their contribution to shoulder and elbow torque. By characterizing the impact of the lower extremity on the kinetic chain, we seek to optimize pitching mechanics while minimizing potentially injurious upper extremity torques during pitching. He is currently a Doctoral Student in the COOR Laboratory and the Musculoskeletal Biomechanics Research Laboratory (MBRL). Additionally, he serves as the interim study coordinator for the PAC-12 funded research study: Biomechanical metrics to improve performance and reduce elbow injuries in baseball.

Oscar Vila Dieguez, MSc, PT

Doctoral Student
2020-Present
 
Oscar completed his Bachelors of Science in Physical Therapy in 2014 at the University of Gimbernat-Cantabria, Spain. In 2018, he earned his Master of Science in Kinesiology & Health Studies at the University of Regina, Canada. His previous research has involved the use of wearable sensors to study of shoulder injuries in swimmers and their relationship with trunk roll and upper limb position during freestyle swimming. 
     At USC, Oscar will investigate the underlying mechanisms of patient improvement with exercise interventions for rotator cuff tendinopathy. Specifically, he will determine whether clinical improvements can be explained by changes in neuromuscular factors, muscle-tendon structure and psychosocial variables. This will help identify biomarkers to optimize delivery of treatments and maximize improvement of patient reported outcomes.
 
 

Matt Heindel PT, DPT

Doctoral Student
2021-Present

Matt completed his undergraduate degree in Applied Human Biology at Seattle Pacific University and his Doctorate in Physical Therapy at the University of New England. He then received his orthopedic residency training at the Sports and Orthopedic Department at Nationwide Children’s Hospital before pursuing his PhD in Biokinesiology at USC under Dr. Michener.

     His research is working to define the relative contributions of tendon structure and brain activity to symptom severity and clinical outcomes in those with rotator cuff tendinopathy. This work will help identify patient-specific targets for intervention by better understanding the factors that contribute to non-recovery in those with rotator cuff tendinopathy.

Chethan Reddy, MS, BS
PhD Student
2024-present

Chethan completed his Bachelor of Science degree in Statistics at the University of Chicago and his Master of Science in Kinesiology at the University of Texas at Tyler. Most recently, he served as the Director of Basketball Engineering and Innovation for the Los Angeles Clippers. Prior to that, he worked as a data engineer for the Los Angeles Dodgers. His experience in professional sports has informed his desire to understand skill evaluation and development through the lens of biomechanics.

Chethan is now pursuing his PhD in Biokinesiology at USC,  specializing in biomechanics within the COOR Laboratory under Dr. Lori Michener.
