Research Statement:

As an overarching goal, my lab's research informs our understanding of how cells communicate and establish their own numbers. Through experiments where I have changed the numbers of cells in a vertebrate embryo, I have become particularly interested in the cell cycle, which consists of alternating rounds of synthesis and mitosis separated by two gap phases. Synthesis and mitosis have long been known to play a critical role in homeostasis. More recently, different cell types in an embryo have been shown to occupy one gap phase preferentially. Going forward, my lab is using D. rerio (zebrafish) as a model system to understand how a specific phase of the cell cycle can affect an immature cell's abilities. Using transgenic zebrafish, RNA in situ hybridization and immunofluorescence, we are currently manipulating the cell cycle during embryogenesis and analyzing the effect on different cell types.
