Martha R. Taylor has been teaching biology for more than 35 years. She earned her B.A. in biology from Gettysburg College and her M.S. and Ph.D. in science education from Cornell University. At Cornell, Dr. Taylor has served as assistant director of the Office of Instructional Support and has taught introductory biology for both majors and nonmajors. Most recently, she was a lecturer in the Learning Strategies Center, teaching supplemental biology courses. Her experience working with students in classrooms, in laboratories, and with tutorials has increased her commitment to helping students create their own knowledge of and appreciation for biology. She was the author of the Student Study Guide for ten editions of Campbell Biology.Eric J. Simon is a professor in the Department of Biology and Health Science at New England College in Henniker, New Hampshire. He teaches introductory biology to science majors and nonscience majors, as well as upper-level courses in tropical marine biology and careers in science. Dr. Simon received a B.A. in biology and computer science and an M.A. in biology from Wesleyan University, and a Ph.D. in biochemistry from Harvard University. His research focuses on innovative ways to use technology to improve teaching and learning in the science classroom. Dr. Simon also leads numerous international student field research trips and is a Scientific Advisor to the Elephant Conservation Center in Sayaboury, Laos. Dr. Simon is the lead author of the introductory nonmajors biology textbooks Campbell Essential Biology, Seventh Edition, and Campbell Essential Biology with Physiology, Sixth Edition, and the author of the introductory biology textbook Biology: The Core, Third Edition.Jean L. Dickey is Professor Emerita of Biological Sciences at Clemson University (Clemson, South Carolina). After receiving her B.S. in biology from Kent State University, she went on to earn a Ph.D. in ecology and evolution from Purdue University. In 1984, Dr. Dickey joined the faculty at Clemson, where she devoted her career to teaching biology to nonscience majors in a variety of courses. In addition to creating content-based instructional materials, she developed many activities to engage lecture and laboratory students in discussion, critical thinking, and writing, and implemented an investigative laboratory curriculum in general biology. Dr. Dickey is author of Laboratory Investigations for Biology, Second Edition, and coauthor of Campbell Essential Biology, Seventh Edition, and Campbell Essential Biology with Physiology, Sixth Edition.Kelly Hogan is a faculty member in the Department of Biology at the University of North Carolina at Chapel Hill, teaching introductory biology and genetics. Dr. Hogan teaches hundreds of students at a time, using active-learning methods that incorporate educational technologies both inside and outside of the classroom. She received her B.S. in biology at the College of New Jersey and her Ph.D. in pathology at the University of North Carolina, Chapel Hill. Her research interests focus on how large classes can be more inclusive through evidence-based teaching methods and technology. As the Director of Instructional Innovation at UNC, she encourages experienced faculty to take advantage of new professional development opportunities and inspires the next generation of innovative faculty. Dr. Hogan is the author of Stem Cells and Cloning, Second Edition, and co-author on Campbell Essential Biology with Physiology, Sixth Edition.Neil A. Campbell 1946—2004) combined the inquiring nature of a research scientist with the soul of a caring teacher. Over his 30 years of teaching introductory biology to both science majors and nonscience majors, many thousands of students had the opportunity to learn from him and be stimulated by his enthusiasm for the study of life. While he is greatly missed by his many friends in the biology community, his coauthors remain inspired by his visionary dedication to education and are committed to searching for ever better ways to engage students in the wonders of biology.
