After spending most of my professional life as a scientist, I’ve discovered that writing fiction offers a rather different kind of freedom. In science, imagination must ultimately answer to evidence. In fiction, imagination can venture considerably further—although I still prefer to keep one foot firmly planted in science.
That approach has so far led me to write two science-fiction novels that, on the surface, have very little in common.
Genes of the Past is a science-based story that begins with an extraordinary discovery: a half-million-year-old hominin fossil unearthed in the Moroccan desert, carrying the genetic information for a sensory ability lost to modern humans. When scientists discover that gene editing might resurrect this ancient faculty, a groundbreaking scientific investigation becomes a matter of national security. As the implications of the discovery unfold, the line between scientific progress and dangerous ambition begins to blur—with consequences that could change the course of human history.
During my tenure as Chief Scientist at the Pacific Northwest National Laboratory, I became interested in the importance and power of chemical signaling across organisms, from microbes to plants to humans. Realizing how much we still don’t understand about these molecular pathways gave me the premise for Genes of the Past.
The Prairie Dogs and the Alien takes a rather different approach. Rupert, the mayor of a Colorado prairie dog town, faces an existential threat to his community. When he sends out a desperate plea for help, the response comes from an unexpected source—an extraterrestrial civilization. What follows is a humorous first-contact adventure involving prairie dogs, humans, aliens, and some uncomfortable questions about how we treat our planet.
The inspiration for this story came from a prairie dog town in Berthoud, Colorado, that I pass by regularly. When I noticed a sign announcing that the land was slated for commercial development, I decided to help the little fellows, if not in real life, so at least in fiction.
