Research Interests: 

Retinoblastoma is a childhood eye cancer that develops in response to mutations in the RB1 tumor suppressor gene. While RB1 regulates proliferation in many cell types, only cells within the retina routinely form cancers when RB1 function is lost. Our research aims to characterize the cell type-specific signaling pathways that collaborate with RB1 inactivation, as a means to identify therapeutic targets for retinoblastoma and other cancers.
