Professional Statement

I am a clinician scientist ophthalmologist with advanced training in genetics, neuroscience, and glaucoma patient care. I am committed to improving our understanding of glaucoma, a potentially blinding neurodegenerative disease of the optic nerve and retinal ganglion cells (RGCs), which will hopefully lead to the development of new diagnostics and therapeutics. Accordingly, my primary basic research objectives are to understand the earliest events that occur in mice with experimental glaucoma (elevated intraocular pressure, or IOP) and to elucidate the mechanisms that govern RGC injury, resistance, and recovery. My lab assesses RGCs and interacting cell types with a variety of techniques such as electrophysiology, visual behavior testing, single cell RNA-sequencing (scRNA-seq), and RGC isolation and culture. Current projects in my laboratory include: 1. Mechanisms of neurovascular unit dysfunction in early stage experimental glaucoma. We have discovered that retinal capillary plexi and a variety of neuronal cell types are differentially susceptible to IOP elevation. This projects aims to understand the mechanisms that underlie these relationships and how they may be altered to modify disease outcomes. 2. Mechanisms of RGC survival and neurite recovery in cell culture. Using a novel immunopanning + FACS based system, we can now isolate RGCs with exceptional fidelity. When these RGCs are cultured, we observe a wide range of survival and neurite extension phenotypes. This project aims to understand the intrinsic mechanisms that govern these RGC responses. 3. Gene expression changes in early stage experimental glaucoma. After exposure to mildly elevated IOP for a variety of durations we isolate RGCs using the same technique described above and perform scRNA-seq. By studying early stage disease, this project aims to identify RGC and RGC subtype specific targets that modulate disease onset and severity. 4. Mechanisms of neuroprotection in glaucoma. We are currently exploring neuroprotection in glaucoma in two ways. First, since some clinical evidence suggests that increased serotonin signaling is neuroprotective against glaucoma, we are assessing the virtually unstudied role of serotonin signaling in mouse retina, RGCs, and experimental glaucoma. Second, we are studying the molecular mechanism of brimonidine, a common IOP-lowering eye drop with known neuroprotective effects.
