Clinical interests
My professional interests focus on the discovery and implementation of diagnostic laboratory tests to evaluate patients with a variety of immune based disorders.

Research interests
My research interests include work on the immunologic and virologic aspects of immune mediated disorders. Currently, I investigate immune and viral factors associated with pathogenic processes within the eye. I have studied the retinal pigment epithelial (RPE) cell extensively as an important immunoregulatory cell and tracked its role in ocular immunity. Over the years, both animal model systems and a human RPE cell model have been utilized to study viral immunopathology. We have developed a murine coronavirus model, experimental coronavirus retinopathy, which identifies how a virus can trigger a retinal degenerative process. These studies revealed both a genetic predisposition and an immune component in this disease. We are continuing to explore the genetic and molecular basis of this autoimmune component of retinal tissue damage.

RPE cells are key players in the first-line defense against invading organisms. Another area of active research is the exploration of innate immunity within the retina. TLRs are critical recognition receptors in the host defense against microbial pathogens and play pivotal role in innate immunity. Using real time PCR analysis of TLR gene expression, we identified the presence of TLRs (TLRs 1-7 and 9-10) in human RPE cells. Moreover, TLR signaling in the RPE cells results in the production of several cytokines, chemokines and adhesion molecules. We are continuing our studies to further define the role of this epithelial cell in innate and adaptive immune responses.

More recently, research efforts have been focused on role of cytokines in regulating and modulating immune responses and immune mediated diseases. Specifically, I have been studying these molecules in vasculitis, infection, cardiovascular disease & atherosclerosis and transplant rejection. To date, our studies are attempting to bring together the current information concerning the role of cytokines in the development, progression, and complications of these inflammatory conditions and to identify their possible role as biomarkers of early inflammatory disease.
