How do visual systems sample and process behaviorally meaningful input, and how can the underlying neuronal networks adapt to changing sensory demands?
We are interested in how visual systems sample and process behaviourally meaningful information, and how processing can adapt to changing environment. Working primarily on the visual system of the zebrafish, we use a combination of 2-photon imaging of genetically encoded fluorescent biomarkers, patterned visual stimulation and computational modelling to study how the neural representation of the outside world evolves as it trickles through the network, from retina to the brain and behaviour.
We are also keen users of modern consumer-oriented manufacturing techniques such as 3D printing of the use of microcontrollers to modify our equipment and to build new and highly specialised equipment from scratch.
There will be a range of projects available suited for candidates with different skillsets and expectations, from molecular genetics and physiology to computational modelling and robotics.
