Areas of Interest
My research interests are in human visual perception and perceptual learning. Current work is focused in three areas:
(1) Elucidating the sensory information and internal models people use when actively moving and navigating within their environment.
(2) Understanding how information from multiple sensory modalifies is integrated for perception and visuomotor control.
(3) Working out how sensory data is used to construct internal models of the physical laws governing the environment and how these models shape our perception of the world.
Techniques I use to investigate these issues include: behavioural experiments and psychophysics, stereoscopic presentation, 3D immersive virtual reality, haptic robotics, machine learning and Bayesian modelling.
