Research Keywords

biomechanics, multijoint movement, impact, motor control, neuroscience, mechanical engineering, injury prevention, performance, sports, dance, music, clinical populations, ergonomics, rehabilitation engineering

Detailed Statement of Research Interests

Dr McNitt-Gray’s research focuses on the control and dynamics of physically-demanding goal-directed movements of daily living. Hypotheses tested target mechanisms organisms(including humans)use to control energy transfer during interaction with their environment. This is accomplished by integrating biomechanics-based experimentation, field work, mathematical and dynamic modeling techniques, and computer simulation.
