Research InterestsMy laboratory studies the regulation of growth during neural development and disease. Cell division must be carefully regulated during brain development to ensure that the resulting tissue is the appropriate size and contains the correct proportion of each specialized cell type. If the precise balance of cell types were altered in the brain, then the different neurons and glia would not be able to work together to process information. Many of the genes that control growth during development are also involved in regulating cell division following brain injury or in certain degenerative processes. In addition, these genes are often mutated in cancer cells. Therefore, by studying the regulation of growth during development, we can learn about the cause and progression of a variety of diseases in the central nervous system. This may ultimately lead to the design of better treatments for neural injury, degeneration and cancer. The retina is a specialized region of the central nervous system that receives and processes visual information. Like the rest of the central nervous system, injury, degeneration and cancer involve changes in the growth properties of retinal cells. We use a wide range of experimental approaches to study how cell division is controlled during retinal development and disease. Methods currently being used in the lab include genetically engineered mice, replication incompetent retroviral vectors suitable for in vivo studies, explant culture systems, microarray hybridization, and to extended our observations to human retinopathies we use normal and diseased human tissue and monkey samples. Experimental approaches that are under development include retinal physiology (ERG), electron microscopy, cell sorting, in vivo mouse models of retinoblastoma, and computational modeling of proliferation during development.
