Research interests

Professor Baldridge’s research concerns the structure and function of the vertebrate retina.  He has particular interest in neuromodulation in the outer retina.  Another major interest is calcium dynamics of retinal ganglion cells (RGCs), particularly in relation to RGC death during conditions like glaucoma.
