Dr. Joshua Gordon is the Director of the National Institute of Mental Health. Dr. Gordon is a psychiatrist who has treated patients with disorders like anxiety and depression. He also does research aimed at understanding what is happening in the brain in people with these disorders. Much of his research has focused on how brain circuits work—pathways of nerve cells connected across the brain that scientists believe are central to how the brain functions. Dr. Gordon’s early interest in science was sparked by the PBS show NOVA. What he loves about science is asking questions and trying to figure out how to answer them. Along with science, he is an avid cycler, and he recently spent a summer pedaling across the United States from California to Delaware.
