He has discovered fundamental principles by which networks of the cerebral cortex are wired during development and change dynamically during learning. His laboratory has identified gene networks underlying cortical plasticity, and pioneered high resolution imaging methods to study cells, synapses and circuits of the intact brain. Recently, his group has demonstrated novel mechanisms underlying disorders of brain development, and proposed innovative strategies for treating such disorders.

  • Christopher A. Walsh, MD, PhD—Senior Science Advisor

    Dr. Christopher A. Walsh is Bullard Professor of Neurology and Pediatrics at Harvard Medical School, Chief of the Division of Genetics, and an Investigator of the Howard Hughes Medical Institute at Children's Hospital Boston.   He completed the MD and PhD degrees at the University of Chicago, neurology residency at Massachusetts General Hospital, and a fellowship in genetics at Harvard Medical School. At the Beth Israel Deaconess Medical Center, his lab studied developmental disorders of the human cerebral cortex, identifying collaboratively more than a dozen genes mutated in human developmental brain disorders, associated with mental retardation, epilepsy, and autism. Dr. Walsh has also pioneered the study of these genes to provide mechanistic insights into human cerebral cortex development and function. Finally, he discovered that some genes mutated in human developmental brain disorders were targets of the evolutionary processes that distinguished humans from our primate ancestors.
