Black-haired and slightly balding, John Singer is the director of the Mount Dragon facility located in the New Mexico desert outside of Engle. On the plump side, John has a mild face that is well tanned and cheerful. His legs are stubby and are equally tanned, visible and offset by the white shorts he wears. His heavy boots reflect the civilian version of the Humvee he drives, along with all other employees of Mount Dragon. The former Morton Professor of Biology at Cal Tech, Dr. Singer is one of the few long term employees of Mount Dragon.
