I love to look, and my research often has a distinctly visual component. I work on embryos, usually Drosophila embryos, and I have a long-term interest in the interrelationship between the cell cycle and cell determination. A few years ago I discovered that the Drosophila embryo comes naturally endowed with a fate map inasmuch as, immediately following the first round of cell determination at cellular blastoderm, groups of cells newly embarked on different developmental trajectories lose their prior mitotic synchrony, and begin dividing at specified times.

Mitotic domains reveal early commitment of cells in Drosophila embryos.
