The developmental biology program combines research activities centered in the Institute of Neuroscience with those in the Institute of Molecular Biology and the Institute of Ecology and Evolution. Several laboratories (Eisen, Guillemin, Kimmel, Miller, Postlethwait, and Westerfield) use zebrafish as a model in which to study the mechanisms underlying vertebrate development. Other research groups study development in the fruit fly (Doe, Guillemin, Herman, Prehoda), the mouse (Gardner, Guillemin, Niell, Stankunas, Sylwestrak, Zemper), the three spine stickleback (Cresko, Kimmel, Postlethwait), the nematode (Bowerman, Libuda, Phillips), Neurospora (Selker), and evolving gene families (Cresko, Kimmel). Members of all of these laboratories actively share information and resources in this diverse and rapidly moving field. In addition to a graduate research training program, a weekly journal club, and joint research group meetings, the developmental biologists participate in a yearly symposium on a topic of interest selected by graduate students in the participating laboratories.
