Research Focus

I am interested how we perceive the world during movement. As well as being an interesting and important question it represents an approachable and answerable version of the broader (but unanswerable!) question "how does the brain work". Clarifying our understanding of perception during movement provides insight into the principles of brain processing in general. On a practical level, it is important to understand how we process information as we move around since we are almost always moving around!

My laboratory investigates how we represent our position, orientation and motion through the world and the location and timing of events in the world. My emphasis is on how information coming from multiple senses at the same time is combined to achieve this. My students and I measure eye, head and limb position and perception while stimulating the vestibular, visual, tactile and auditory senses in various ways and in various combinations. We use various real and simulated sensory environments, including electrical stimulation, virtual reality, underwater submersion, loudspeakers, lights, headphones, vibrators, screens and photographs to gain independent control of the various senses.
