About the Contributors

John M. Butler holds a doctoral degree in chemistry from the University of Virginia and is the author of eighty research articles and book chapters on human DNA, including essays on Y-chromosome and mitochondrial DNA as applied to human-identity testing. He has received a number of awards in the field of forensic genetics and is the author of the award-winning textbook Forensic DNA Typing, now in its second edition. In July 2002, Butler received the Presidential Early Career Award for Scientists and Engineers from President George W. Bush in a White House ceremony for his work in pioneering modern forensic DNA testing. He is currently employed as a research chemist in the Biochemical Science Division at the U.S. National Institute of Standards and Technology, where he directs a project team developing new DNA technologies for forensic and human-identity applications.

David A. McClellan earned a PhD from Louisiana State University. He is an assistant professor of integrative biology at Brigham Young University, where he researches the theoretical aspects of protein and DNA molecular evolution. This includes mathematical and statistical modeling, software and other methodology development, and empirical analysis of protein-coding gene sequences.

D. Jeffrey Meldrum holds a PhD in anatomical sciences with an emphasis in physical anthropology from SUNY at Stony Brook. As an associate professor of biology at Idaho State University, he teaches human anatomy and evolution. His research in evolutionary morphology and paleontology centers on primate and human locomotion.

Matthew Roper, who received a master’s degree from Brigham Young University, is a resident scholar at the Neal A. Maxwell Institute for Religious Scholarship.

John L. Sorenson, who earned his PhD at UCLA, is emeritus professor of anthropology at Brigham Young University. His major interest has been in applied sociocultural anthropology. He served as head social scientist at General Research Corporation in Santa Barbara, California, and was founder and president of Bonneville Research Corporation in Provo, Utah. He has published extensively in Mesoamerican archaeology.

Trent D. Stephens holds a PhD in anatomy and embryology from the University of Pennsylvania. He is a professor of biology at Idaho State University, and his research in embryology and teratology focuses on the mechanisms of limb development.

Brian D. Stubbs earned a PhD from the University of Utah and now teaches English, Spanish, and ESL at the College of Eastern Utah—San Juan Campus, where he also does research on the Ute, Hopi, and Tewa languages spoken in the region.

Michael F. Whiting holds a PhD in entomology from Cornell University. He has received multiple National Science Foundation (NSF) grants (including the prestigious NSF CAREER award), regularly serves on review panels for NSF, and is director of Brigham Young University’s DNA Sequencing Center and an associate professor in Brigham Young University’s Department of Integrative Biology.
