Jacob Rammer

Using advanced biomechanical instrumentation and modeling techniques, Dr. Rammer’s research seeks to better understand mobility and participation of people with disabilities in both laboratory and community settings. His connected health technology approach leverages mobile applications and devices to quantitatively document mobility and participation. Ultimately, implications of this work will lead to improved clinical care, rehabilitation outcomes, and quality of life for people with disabilities.
