The studies carried out by our laboratory predominately focus on disease pathogenesis and the interplay between the immune and neuroendocrine systems. We mechanistically and therapeutically investigate the events of inflammation and innate immunity using a model of ocular infectious disease.
This includes analyses of: host inflammatory cells (macrophages, neutrophils, T cells - both in vivo and in vitro), extracellular matrix and adhesion molecules, cytokines/chemokines, Toll-like receptors and other related molecules using a number of molecular, cellular and immunohistochemical techniques. Ongoing NIH-funded studies examine how the neuropeptide, vasoactive intestinal peptide (VIP), influences T cells and the production of IL-17, nerve regeneration, and the production of endogenous lipid mediator circuits. In addition, my laboratory is defining the clinical applicability of VIP as a treatment modality in the eye. Additionally, other projects include: 1) a collaborative project with Dr. Jena Steinle looking at the role of inflammation in diabetic retinopathy, and 2) how neutrophil transdifferentiation contributes to disease pathogenesis.
I participate in the Year I Curriculum for medical students by teaching Gross Anatomy. I also contribute individual lectures to the Biology of the Eye course (ANA 6050, 7055, PYC 7050, and BIO 6055, 7055).
If you have interest in joining our lab, please contact me by email. The lab is particularly interested in undergraduate students who are able to commit 1+ years of research. We also provide opportunities for medical students interested in research through the summer internship program offered by the Department of Ophthalmology.
