About me

I am Lecturer (equiv. Assistant Professor) in the School of Biological and Behavioural Sciences at Queen Mary University of London.

My research interests include saccade planning, transsaccadic perception, integration and use of peripheral and foveal information, object viewpoint perception, perceptual inference, and the interaction between complex objects and behaviour.

My research uses behavioural and psychophysical tecniques coupled with eye-tracking and computational modelling.

Research

Transsaccadic perception

Humans move their eyes 2-3 times per second, introducing a large discontinuity between the low-resolution, presaccadic, peripheral view of an upcoming eye-movement target, and the high-resolution, fovel, postsaccadic view of this target. Despite this constant flux of changing visual input, we maintain a remarkably stable percept of the world. How does the visual system achieve this?

3D object perception

How do we perceive 3D objects, and what can this tell us about how we picture things in our mind’s eye?

Saccade sampling and information uptake

Why do humans move their eyes to certain areas of the world, and how do they use these eye movements – saccades – to sample information?

Past history and prediction

How does our oculomotor system predict what’s going to happen, and how does this affect oculomotor planning?

Inferences from objects

Our world is full of complex objects – how do the properties of these objects influence perception and eye movements?
