    Research Interests: I collaborate with Dr. Dana Garcia. Research is oriented toward understanding the mechanisms through which light- and dark-adaptation are accomplished in the retina of fishes. Of particular interest are those processes involved in regulating pigment granule movements in the retinal pigment epithelium (RPE). Much of the effort has been oriented toward discovering how acetylcholine activates light-adaptive pigment granule dispersion in retinal pigment epithelium, both in terms of the cell surface receptors involved and the downstream signaling processes.

    Research Interests: Cell biology and neurobiology of the retina.

    Bio: Ever since high school, I’ve been interested in how cells communicate with one another using signaling molecules.  As a graduate student in Beth Burnside‘s laboratory at the University of California at Berkeley, I was entranced by the potential of fish retinas as model systems for studying cytoskeleton, cell motility, and cell signaling.  As a professor, I pursue my interest in those topics by studying how nerve cells in the retina communicate with the retinal pigment epithelial cells. In fish, the retinal pigment epithelium has long, apical projections which under daylight conditions fill with melanin pigment granules.  In the dark, the pigment granules leave the apical processes and reside in the base of the cell around its nucleus.  These movements are extensive, making them a good study system for understanding the signaling pathways and mechanical systems that regulate and execute organelle transport.

    Research Interests: The C. difficile associated diarrhea (CDAD) is a major concern in hospitalized elderly patients. This condition is induced by certain antibiotics given during either surgery or treatment for bacterial infections which wipe out the normal microflora in the gut resulting in overgrowth and toxin production by C. difficle. Metronidazole is used as first line of defense but has a high relapse of the disease with development of resistance against it. The mechanism of action of metronidazole is elusive and it has been proposed that formation of nitoso- radicals and nitrous oxide exert nitrosative stress on bacterial cells eventually killing them. Using molecular and genetic tools we have identified genes in C. diffcile with altered expression upon exposure to metronidazole and related nitroaromatic drugs. However, we could not detect the nitrous oxide production under the tested condition, indicating that it may not play a significant role in bacterial killing. We also attempted to isolate metronidazole resistance mutants in order to understand the resistance mechanism; however the resistance was unstable and lost upon storage and sub-culturing. Our study has identified the genes that may be involved in metronidazole resistance.
    My other areas of interest are antimicrobial resistance, regulation of biofilm and bioremediation of industrial pollutants.
