Scientifc Interest

My main scientific interest is to analyse retinal signal processing on the cellular, network and behavioural level.  I aim to understand the functional role of electrical synapses  in the retina and to elucidate the role of individual cell types,  e.g., wide-field amacrine cells or horizontal cells.
