Professional Summary:

As a specialist in cornea and external diseases of the eye, I treat a wide range of eye problems and perform a variety of surgical procedures including corneal transplantation, cataract surgery, conjunctival tumor surgery, and transplantation of the artificial cornea when standard corneal transplantation has failed.

One of the most common reasons for corneal transplantation is corneal edema. Edema of the cornea develops from loss of corneal endothelial cells and causes irreversible vision loss in thousands of people yearly. Beyond surgical transplantation of the endothelial cell layer with human donor corneal tissue, no vision-restoring treatments are available. My research investigates the physiology regulating corneal hydration to advance future treatments for these patients. There are two main projects in my lab. The first looks at characterizing changes occurring in endothelial cell monolayer intercellular junctions and passive paracellular transport properties at low and high cell densities. Clinically, patients do not experience deterioration in vision or corneal edema until very low densities. The molecular basis for this observation is unknown. This project investigates changes in the apical junctional complex and monolayer permeability of the endothelium. The second project examines the mechanisms and regulation of active water transport out of the cornea. Using Ussing chamber physiology techniques, my lab is isolating the contributions and regulation of various ionic currents across the corneal endothelium with a focus on the contributions of potassium channels, bicarbonate and carbonic anhydrase inhibitors.
