Neurobiologist Carla Shatz, director of Stanford University Bio-X, has focused her research on how early brain circuits are transformed into adult connections during critical periods of development. Her work, which focuses on the development of the mammalian visual system, has relevance not only for treating disorders such as autism and schizophrenia, but also for understanding how the nervous and immune systems interact. This interview provides insights about what you can you learn from ski racing and how she got inspired to study neuroscience after her grandmother’s stroke.
