I have two Ph.D.s, one in Molecular and Cell Biology from the University of California at Berkeley (1994), and one in Religious Studies from Yale University (1986). After finishing my Berkeley Ph.D. I taught embryology at California State University in Hayward, did post-doctoral research at Berkeley, and worked as the supervisor of a medical laboratory in Fairfield, California. In 1998 I moved with my family to Seattle, where I am now a Senior Fellow at the Discovery Institute's Center for Science & Culture.
I have published scientific articles in Development, Proceedings of the National Academy of Sciences USA, BioSystems, The Scientist and The American Biology Teacher. I am also author of Charles Hodge's Critique of Darwinism (Edwin Mellen Press, 1988) and Icons of Evolution: Why much of what we teach about evolution is wrong (Regnery Publishing, 2000). I am now working on a book criticizing the over-emphasis on DNA in biology and medicine.
