I
study the organization of human
action. The goal of my research is to develop a comprehensive science
of embodied cognition through the study of movement. My research brings
together Cognitive, Neurophysiological and Dynamical systems approaches
in the study of action.
I
am interested in all aspects of
Perception-Action systems, but especially in three programs of
research: (1) Posture and Balance (2) Voluntary
goal directed actions
and (3) Timing in repetitive and rhythmic movements (Please follow
links for
details and publications). My research borrows from principles of complex systems,
where the behavior of a system of many
components is significantly different, yet simpler than the behavior of
the components themselves.
