Dr. Gregory Stock explores the larger evolutionary significance of our recent technological progress. This interest led to his 1993 book Metaman: The Merging of Humans and Machines into a Global Superorganism. He currently directs the Program on Medicine, Technology, and Society at UCLA's Medical School, where he is a visiting professor. He is also a senior fellow at the Center for the Study of Evolution and the Origin of Life. He co-organized the first major symposium on human germline engineering in 1998, and he continues to speak often on radio and television. His latest book, Redesigning Humans, discusses the impact of genomics and bioinformatics on future human evolution. He is also known for his thought-provoking value-clarifying questions. The Book of Questions, now in its 55th printing, has sold over 2 million copies and been translated into 17 languages.
