Jessica Gumerson, PhD

My research has centered on understanding the underlying cellular mechanisms and identifying novel treatments for neurodegenerative, neuromuscular, and inflammatory diseases. My current focus is on diseases that affect the eye like uveitis, retinitis pigmentosa, and age-related macular degeneration.

Earlier in my career I worked on congenital and adult-onset muscular dystrophies associated with mutations in dysferlin and members of the dystrophin-glycoprotein complex. While these are very different diseases from those that affect the eye, the underlying cell biology share common features. For example, inherited mutations can have a negative consequence on calcium signaling, cell membrane biology, and cytoskeletal dynamics, which ultimately cause different diseases depending on the cell type affected (i.e. muscle myofibers or retinal neurons).
