Assistant Professors: Brooke McCartney (left), Justin Crowley (center), and Tina Lee (right)Dr. McCartney, a cell and developmental biologist, investigates the intersections between signal transduction and cytoskeletal organization in Drosophila using the APC family of tumor suppressors as a model. Using a combination of multi-photon imaging techniques and physiological recordings, the research of Dr. Crowley, a neuroscientist, centers on understanding the formation of neural circuitry in the visual system. Dr. Lee, also a cell biologist, uses complementary in vivo and in vitro approaches to study the mechanisms by which changes in cell physiology regulate trafficking steps within the secretory pathway of mammalian cells.
