Dr. Van Emmerik's research is in the area of motor control and coordination. In his research, he applies principles from complex and nonlinear dynamical systems to the study of posture and locomotion. The particularly emphasis in his research is on mechanisms of stability and adaptability in movement coordination. An important research focus is the role of variability in the control of movement. He has extensive experience in the area of balance and gait disorders due to aging and neurological disease, such as Parkinson's disease and Multiple Sclerosis.
