My research investigates how the brain makes sense of the world viewed by the eye. Although I'm interested in general problems that cut across all areas of visual processing, I use insects as an ideal model for tackling problems at theoretical, physiological and behavioural levels. With a visual system that accounts for as much as 30% of the lifted mass, some flying insects invest more in vision than any other animal.
What happens to the abundance of information collected by such large eyes? How has the brain evolved to optimally extract the features from scenes that are most relevant to the behaviour adopted? These are the kind of questions we ask.
