We study the multicellular interactions between neurons and glia in the brain with a primary focus on the development, plasticity, and regeneration of myelinating oligodendrocytes. Techniques include high-resolution optical imaging in combination with molecular labels, genetic manipulation, and sensors of cellular physiology.
