Research Interests: Epigenetic regulation of transcription. Development and disease processes in the vertebrate retina.

My lab is interested in epigenetic mechanisms of gene regulation in the vertebrate retina. Beyond the As, Cs, Ts, and Gs that make up the genetic code within cells, eukaryotic genomes acquire heritable and reversible chemical modifications that play a large role in influencing gene expression. Genome-wide patterns of these epigenetic modifications do not change the actual DNA sequences, yet can be passed on to subsequent generations much like the genetic code. In contrast to genomic DNA, epigenetic patterns are fluid and often change allowing cells the flexibility to alter patterns of gene expression based on environmental cues.  In my lab we use the vertebrate retina to study DNA methylation, an epigenetic modifier of genomic DNA. Using the developing chicken, the mouse, and the human eye, we are investigating the role of DNA methylation in transcriptional regulation of retina-specific genes. These studies will advance the understanding of gene regulation in the visual system, which will ultimately provide us with better tools for understanding and treating retinal diseases and disorders.
