Steven Fisher and the Retinal Cell Biology Lab housed in the Neuroscience Research Institute is dedicated to studying the cell biology of vertebrate retina using a variety of cell and molecular techniques but with an emphasis on biological imaging. In the nearly 40 years since its establishment the lab has approached many questions from the development of synaptic connections to photoreceptor outer segment renewal and disc morphogenesis to more recently mapping the array of the whole retinal astrocyte populaton through the use of large scale, high resolution imaging.
