Research Focus:

Research program on the molecular genetics of the Drosophila eye.  Our research has focused on the molecular genetics of signal transduction, calcium modulation, eye development and protein trafficking in Drosophila photoreceptors. The aim of our research program has been to identify signaling molecules in complex pathways, for the purpose of pinpointing candidate genes in heterogeneous retinal diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP).  We focused on trafficking mechanisms that are critical for the development and maintenance of photoreceptors.  We took a multidisciplinary approach for unraveling the basic mechanisms retinal function. Further, our work was focused on identify novel disease genes, and improving our understanding of disease pathogenesis in order to better diagnose, treat and prevent blinding retinal diseases such as AMD and RP.
