Visual Cognitive Neuroscience
- visual working memory
- attention
- conscious perception
- capacity limitations
- fMRI
- pattern classification

The overall objective of my research is to examine how the brain processes visual information. In particular, I am interested in understanding how it is that neural activity can give rise to conscious perception. To address this question, my research focuses on the limited nature of visual short-term (working) memory and attention, as well as by examining how these capacity-limited processes may support conscious perception. My research also explores the ways in which visual short-term memory and attention interact in everyday tasks (e.g., visual search). To answer these questions, I use a combination of behavioural methods, neuroimaging (fMRI), and electrophysiological methods (EEG/ERPs).
