Research:

My research is focused on examining the changes in human movement patterns on 3 time-scales of change: (1) short-term adaptation; (2) learning; and (3) development and aging. These studies have shown how motor patterns can be affected by changes to the task, environment, and individual. My research has shown that the availability of information from the environment and task difficulty have a compensatory effect on the pattern of force produced by an individual. Another area of research that I am interested in consists of studies of how the aging and developmental processes affect the adaptability of the individual and diminishes their ability to his/her environment. I also study the acquisition of skill and decomposing the patterns of change in performance over the course of practice.

Compensatory tradeoffs in the uncertainty of human force produced as a function of task difficulty and environmental information. The force output is more unpredictable when the task is easy and there is an abundance of information from the environment.
