Biography

A major research theme is sensory dynamics: How do sensory processes evolve over time? What temporal information are we sensitive to and how do we perceive time?

Other research interests include:

Effects of clutter on visual performance (Visual crowding);

Augmented reality and cognitive load;

Multi-sensory processing;

Binocular interactions - stereopsis and rivalry;

Visual motion processing and spatio-temporal channels;

The relationship between attention and body dissatisfaction
