Research Interests:

My lab focuses on understanding mechanisms of neuronal aging and white matter-optic nerve stroke. White matter strokes correspond to approximately 40% of all strokes in the US, yet have been difficult to study in vivo. The optic nerve is actually an isolated CNS-white matter tract, and thus is excellent for studying questions of white matter stroke. My lab has generated the first clinically relevant models for optic nerve stroke (nonarteritic anterior ischemic optic neuropathy, NAION) in rodents and primates. The NAION models are the first in vivo stroke models that specifically targets white matter, and are relevant for one of the most common strokes affecting individuals. We use these models in a variety of species: to evaluate neuroprotective approaches to early stroke treatment, genetic response to white matter stroke, and primate-specific responses.

My research is also dedicated to identifying genes predisposing the retina to age-related neuronal diseases, such as macular degeneration. Our working hypothesis is that as neural tissues age, specific changes in gene expression occur that predispose or weaken the individual's ability to resist subtle gene differences and stress. We have identified a number of genes that change during aging, and are studying these gene's roles in contributing to age-related disease.

Clinical Speciality:

Comprehensive Ophthalmology, Ophthalmic Genetics

Lab Techniques and Equipment:

Current specific projects include mapping retinal neuron function and regeneration after stroke, and analysis of drugs that may be effective following stroke. We perform immunohistology, confocal microscopy, basic molecular biology (PCR and RNA-based PCR) and computer-aided stereotactic intracranial and intravitreal injections and evaluation of NAION by multiple electrophysiological methods.
