Research Interests

I use the model organism Drosophila melanogaster to study fundamental problems in nervous system development. How do newly born cells know what types of neurons they're supposed to be? How does a neural stem cell produce distinct types of neurons at the right time during development? How do insect nervous systems reorganize during metamorphosis to accommodate radical transformations in body plan from limbless larvae to adults designed for mating and dispersal? And how have nervous systems evolved variations on the basic arthropod model to enable novel brain functions or dramatic differences in appendage type and number?
