Research Interests

My interests are in sensory processes and perception, especially in the senses of vision and touch. Much of my work has focused on control processes, such as binocular rivalry in vision and pain gating in somesthesis, by which some sensory signals are able to amplify or attenuate others. I have also helped to establish that tactile textures are perceived by means of two sensory mechanisms: spatial coding for coarse textures, and vibration coding for fine ones. Currently, I am writing about the diversity of sensory processes within the animal kingdom.
