Mark Okuda received his BA in biology with a minor in chemistry from the University of the Pacific. He went on to receive his MA in natural science from San Jose State University. Mark taught for 33 years at Silver Creek High School and currently serves as an adjunct faculty member at Evergreen Valley College teaching human heredity and forensic biology. During his tenure as a high school science teacher, Mark was the recipient of the Santa Clara County Teacher of the Year, Synopsys Outstanding Science Teacher Award, East Side Union High School District Innovative Teacher Award (Forensic Science), and National Biotechnology Education Conference Teacher Award and held a patent for a biotechnology kit marketed by Bio-Rad entitled "Secrets of the Rain Forest."

Frank H. Stephenson received his PhD in molecular biology from UC Berkeley and performed postgraduate work at UC San Francisco Medical School. He spent several years with Berlex Biosciences as a senior research scientist prior to joining the Technical Training Department at Life Technologies, where he teaches forensics, DNA sequencing, and real-time PCR. Frank has taught molecular biology with the UC Berkeley Extension program and, for ten years, served as a part-time faculty member with Foothill College, where he conducted evening classes in PCR. Dr. Stephenson has published several books in the biotech field, including DNA: How the Biotech Revolution Is Changing the Way We Fight Disease and Calculations for Molecular Biology and Biotechnology: A Guide to Mathematics in the Laboratory. This textbook evolved from summer workshops in forensic and DNA analysis given at Life Technologies to high school teachers and students in collaboration with his coauthor, Mark Okuda.
