Current interests and expertise

My research is focused on the study of human sensorimotor control systems. Neurophysiological and behavioral approaches are used as complementary means to investigate the role of proprioceptive, exteroceptive, and visual information in the control and regulation of sensorimotor activities (spinal reflexes, force control, postural stability, oculomanual coordination). Vibration-induced perturbations are often used to analyze the functional aspects of the different neurological systems involved in movement control. The occupational aspect of vibration exposure is also of concern in these investigations; current emphasis is on the influence of vibrationvariables on muscle fatigue. Other Areas of investigation include: 1) analysis of motor activities in repetitive tasks involving computer input devices or hand-tools; motor coordination and muscle load pattern are analyzed 3) influence of floor characteristics on leg muscle fatigue and performance; playing and work surfaces are of concern 4) human-machine cooperative control, applications to wheel chairs and other vehicle are investigated 5) quantification of visual fatigue. A combination of classical neurophysiological techniques and mathematical modeling are used in some of the experiments.

Industrial applications

Applications: 1) vibratory environments for operators/workers using vibrating tools or machines or vehicles 2) design of workstation and computer input devices 3) reduction of fatigue
