Marie E. Burns

Clinical Interests

Trained as a biochemist and electrophysiologist, Marie E. Burns studies the temporal regulation of signal transduction mechanisms in neurons. Much of her work has investigated the deactivation of the G protein cascade in photoreceptor cells of the retina. Her future studies will seek to understand the mechanisms by which different G protein cascades yield signals of varying amplitude and durations, such as in the rod and cone photoreceptors in the retina.
