My research addresses the dynamics of attention and perception. I combine empirical experimentation in attention and auditory perception with mathematical and neural modeling using dynamical systems, statistical methods, and artificial neural networks. My goal is the development of quantitative theories that link experimental findings with neurophysiological mechanisms. My dissertation investigated the perception of natural auditory sequences, specifically musical performances, focusing on the development of theoretical approaches that adequately describe responses to complex temporal patterns. As a Reseach Fellow in Cognitive Science my primary focus has been building upon my dissertation research to develop a general theory of attention and time perception in the auditory domain. In Jud Crawford's Auditory Neuroethology Laboratory I am applying related theoretical concepts to modeling the neurophysiology of the auditory system. Additionally, I am working in the General Robotics and Active Sensory Perception (GRASP) Laboratory, applying nonlinear dynamics to the design of intelligent physical agents, and investigating auditory perception through the design of autonomous robotic systems.
