Greg Marchetti is an Associate Professor in the Department of Physical Therapy at Duquesne University. Dr. Marchetti earned an entry level Physical Therapy degree from the University of Maryland and a Master of Science from the School of Health and Rehabilitation Sciences at the University of Pittsburgh. After 17 years of clinical practice in diverse settings, he obtained a Ph.D. in epidemiology with an emphasis in non-communicable disease from the Graduate School of Public Health at the University of Pittsburgh. Greg also currently holds appointments in the School of Medicine, Department of Otolaryngology at the University of Pittsburgh, University of South Florida, and University of Montana. With expertise in epidemiology, measurement, data management and analysis, Dr. Marchetti has conducted research, published and presented nationally and internationally on the clinical measurement of gait and balance, disorders of balance and vestibular impairment, mild traumatic head injury, chronic disease, chronic pain management, differential diagnosis and ergonomics/occupational injuries. He has been a primary investigator on randomized clinical trials for persons with osteoarthritis of the knee, cervical radiculopathy and vitamin D deficiency.
Clinically, Greg serves as physical therapist for the Pittsburgh Catholic Charities Health Care System, a multidisciplinary clinic dedicated to the service of persons without access to health insurance. He holds specialty certifications in ergonomic assessment and worker's compensation service provision and serves as Ergonomic Assessment Specialist for ErgoSmart Consultants and Health Outcomes Analyst for WebPT. He is on the editorial board of the Journal of Neurological Physical Therapy, and serves as peer reviewer for numerous academic publications. Across the physical therapy research realm, Greg has had the privilege of having recent work published Journal of Physical Therapy, Journal of Geriatric Physical Therapy, Journal of Orthopedic and Sports Physical Therapy, Journal of Pediatric Physical Therapy, and the Journal of Neurological Physical Therapy.

An effective instructor must have a passion for giving students the tools to succeed. The classroom should be a psychologically safe, respectful and trustworthy environment where students can develop innovative behaviors through an exploration of the governing values and assumptions behind their decisions and ideas. In this way students are empowered to challenge the status quo and experience true transformational change. Freedom of discourse and permission to be wrong are essential parts of a learner-centric process leading to growth.
