NIH Ruth L. Kirschstein National Research Service Award Individual Predoctoral MD/PhD Fellowship (2018-2021)

Each NIH Institute offers Kirschstein National Research Service Award Individual Predoctoral MD/PhD Fellowships (F30 NSRAs) intended to enhance the integrated research and clinical training of promising predoctoral students who are matriculated in a combined MD/PhD training program and who intend careers as physician-scientists.  Justin J. Grassmeyer, an MD/PhD Scholar at UNMC, has been awarded a 3-year F30 NSRA from the National Eye Institute for his project entitled “Investigating Ca2+-dependent mechanisms of mammalian photoreceptor neurotransmission.” Justin’s research aims to uncover the mechanisms of neurotransmission in the mammalian retina, focusing on rod and cone photoreceptors. Specifically, his project will describe the kinetics, calcium dependence, and proteins that govern neurotransmitter release at the first synapse of the mammalian visual system. The results will be an important contribution to understanding the first steps in visual processing and the mechanisms of sensory perception. Justin completed his dissertation research under the direction of Wallace B. Thoreson, PhD, in the Department of Ophthalmology & Visual Sciences, receiving the PhD degree in May 2019. He will pursue the final two years of his medical school training at UNMC.
