Jeb Kinnison grew up in the Midwest. He discovered science fiction in second grade, starting with Tom Swift books and quickly moving to Heinlein juveniles and adult science fiction. He studied computer and cognitive science at MIT, and wrote programs modeling the behavior of simulated stock traders and the population dynamics of economic agents. Later he did supercomputer work at a think tank that developed parts of the early Internet (where the engineer who decided on ‘@‘ as the separator for email addresses worked down the hall.) He retired a few years ago and began writing science fiction with the Substrate Wars series.
