Research Interests

General

•Human visual perception and the associated information processing mechanisms

•How does our brain construct the world that we perceive?

•Eye tracking methodology

Current focus

•Temporal structure: relations between basic visual input and the resulting perceptual sensations

•Is visual perception continuous, or is it made of snapshots, known as perceptual moments?

•To what extent may stimuli be processed in the absence of awareness?

Methodology

•Psychophysics

•Eye tracking

•EEG/MEG

•CFS, binocular rivalry, stereoscopic stimulus displays

•Computational methods
