Larry Hjelmeland, Ph.D.
Clinical Interests
Dr. Hjelmeland's research is focused on the origins of age as a risk factor for the development of
Age-related Macular Degeneration(AMD). Our current hypothesis is that the genome of the retinal
pigment epithelium (RPE) undergoes a defined set of epigenetic modifications which promote the
disease.
