I hold a doctorate in theoretical biology from the University of Chicago (1971) and teach computer science (mostly) at Thomas College in Waterville, Maine (for list of courses taught and syllabi, click here). My work on scientific and futuristic issues has appeared in many magazines, from Astronomy to Consumer Reports and Robotics Age. My nonfiction books include biology texts and books on careers in science, the privatization of social services, entrepreneurs, and consultants.
I am a member of the Science Fiction and Fantasy Writers of America and have been the monthly book columnist for Analog ever since 1979. Much of my fiction has dealt with implications and potentials of genetic engineering; my "organic future" novels include Sparrowhawk (Ace, 1990), Greenhouse (Ace, 1991), Woodsman (Ace, 1992), Tower of the Gods (Ace, 1993), and Seeds of Destiny (Ace, 1994). Silicon Karma (White Wolf, 1997) was quite well received; a Rocket eBook edition appeared in 1999.
Unto the Last Generation, first available electronically from Mind's Eye Fiction in 1998, appeared with its sequel, Stones of Memory, from Wildside Press in 2000. Wildside also published the collection The Electric Gene Machine and the anthology Gedanken Fictions: Stories on Themes in Science, Technology, and Society, which I prepared to accompany my nonfiction anthology, Taking Sides: Clashing Views on Controversial Issues in Science, Technology, and Society (Dushkin Publishing Group, 6th ed., 2004).
The latest Wildside novels are The Great Flying Saucer Conspiracy and Firefight.
