Personal profile


Dr. Patrick Nalepka received his PhD in Experimental Psychology from the University of Cincinnati within the Center for Cognition, Action and Perception. During graduate study, Dr. Nalepka's research focused on investigating the perceptual-motor processes that underlie the emergence of stable coordinative patterns in complex and dynamic multiagent task contexts, as well as the role constraints play in how such patterns materialize. Since joining Macquarie, his focus has been on investigating the effects embodied artificial-agents (e.g., virtual avatars, robots) have in mixed human-artificial agent teams for coordination, and how such artificial systems should be used to enhance human skill acquisition in perceptual-motor tasks undergoing continual perturbations. Dr. Nalepka's research utilizes nonlinear time-series analyses, dynamical modeling, reinforcement and machine learning, and virtual reality technology.
