Areas of interest
My research interests are in human visual perception and perceptual learning. Current work is focused in three areas.
- Elucidating the sensory information and internal models people use when actively moving and navigating within their environment.
- Understanding how information from multiple sensory modalities is integrated for perception and visuomotor control.
- 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.
