Provo, UT 84602

I grew up in Fairview, Utah, about 50 miles south of Provo. I earned my B.S. in microbiology from Brigham Young University in 1980. I then went to Oregon State University in Corvallis where I earned my Ph.D. in 1985 in microbiology studying bacterial RNA polymerase, with an emphasis in molecular biology. I conducted postdoctoral research at the University of California, Irvine, from 1985-1988, studying plant chloroplast DNA replication and associated enzymes. I was on the faculty at Auburn University in Alabama from 1988-2000, and then moved to BYU as a professor in 2000. I enjoy working with students in the classroom and the laboratory, and sharing my experience and knowledge of molecular biology. I enjoy reading, fishing, and gardening with my wife.
