    Research Interests
    At this time, I am re-directing my research from opioid related signaling in the regulation of intraocular pressure (IOP) to the action of melatonin in regulating aqueous humor dynamics. Because melatonin does not produce the side effects associated with opioids such as morphine, it should be viewed as a better candidate for the therapy of glaucoma, as melatonin similar to morphine and other opioids has been shown to lower IOP in animals and humans, but the mechanism of this effect has not been determined. The goal of my current research is to establish the effect of melatonin on signal transduction events in the aqueous humor producing and secreting non-pigmented ciliary epithelial (NPCE) cells of the eye. Studying these events will help in delineating the mechanism of melatonin-induced reduction of IOP, thus establishing it as a viable alternative in glaucoma therapy.
