Kenneth A. Mason received his undergraduate degree in Molecular Biology from the University of Washington, worked at UC Berkeley, then pursued his PhD in Genetics at UC Davis. He has taught Gentics, Microbial Genetics, Microbiology, Advanced Molecular Genetics, Introductory Biology, and a Genetics Laboratory that he designed.
Dr. George B. Johnson is a researcher, educator, and author. Born in 1942 in Virginia, he went to college in New Hampshire (Dartmouth), attended graduate school in California (Stanford), and is Professor Emeritus of Biology at Washington University in St. Louis, where he has taught freshman biology and genetics to undergraduates for over 35 years. Also Professor of Genetics at Washington University’s School of Medicine, Dr. Johnson is a student of population genetics and evolution, authoring more than 50 scientific journal publications. His laboratory work is renowned for pioneering the study of previously undisclosed genetic variability. His field research has centered on alpine butterflies and flowers, much of it carried out in the Rocky Mountains of Colorado and Wyoming. Other ecosystems he has explored in recent years include Brazilian and Costa Rican rain forests, the Florida Everglades, the seacoast of Maine, coral reefs off Belize, the ice fields and mountains of Patagonia, and, delightfully, vineyards in Tuscany.
A prolific writer and educator, Dr. Johnson is the author of seven nationally recognized college texts for McGraw-Hill, including the hugely successful majors texts Biology (with botanist Peter Raven) and three nonmajors’ texts: Understanding Biology, Essentials of The Living World, and The Living World. He has also authored two widely used high school biology textbooks, Holt Biology and Biology: Visualizing Life. In the 30 years he has been authoring biology texts, over 3 million students have been taught from textbooks Dr. Johnson has written
Jonathan Losos is a Monique and Philip Lehner Professor for the Study of Latin America in the Department of Organismic and Evolutionary Biology and Curator of Herpetology at the Museum of Comparative Zoology at Harvard University. Losos's research has focused on studying patterns of adaptive ratiation and evolutionary diversification in lizards. The recipient of several awards including hte prestigious Theodosius Dobzhansky and David Starr Jordan Prizes for outstanding young evolutionary biologists, Losos has published more than 100 scientific articles.
Susan Singer is the Laurence McKinley Gould Professor of the Natural Sciences in teh dpartment of biology at Carleton College in Northfield, Minnesota, where she has taught introductory biology, plant biology, genetics, plant development, and developmental genetics for 20 years. Her research interests are focused on the development and evolution of flowering plants. Singer has authored numberous scientific publications on plant development, contributed chapters to developmental biology texts, and is actively involved with teh education efforts of several professional societies. She received the American Society of Plant Biology's Excellence in Teaching Award, serves on teh National Academies Board on Science Education, and chaired the NRC study committee that produced America's Lab Report.
