Molecular Biology

update edition of Molecular Biology. She has taught courses in General Biology, Genetics, as well as Anatomy and Physiology at Southwestern Illinois College, McKendree University, and Harris-Stowe University. She received her BA in Biology from Lawrence University in Appleton, Wisconsin, in 1990 and her PhD in Molecular, Cellular, Developmental Biology and Genetics from the University of Minnesota in 1996. Her doctoral thesis studied how alterations in the structure of lactose permease affect its ability to transport sugar across the membrane of E. coli. Following her degrees, she investigated the IL-1 and TNF signal transduction pathways that control apoptosis and immunity at Indiana University School of Medicine. She has most recently studied the various molecules that maintain the stem cell fate in C. elegans at Washington University School of Medicine in St. Louis, MO. She is married and the mother of three children, ages 15, 12, and 8, which always make her realize the role biology plays in personality and development! Michelle R. McGehee earned a BA in Microbiology in 2000 and a PhD in Molecular Biology, Microbiology, and Biochemistry in 2005, both from Southern Illinois University in Carbondale, IL. Her graduate research focused on the genetic and biochemical regulation of lactate fermentation in Escherichia coli and was supervised by Dr. David P. Clark. After graduation, she accepted a postdoctoral research associate position at Texas A&M Health Science Center in College Station, TX, where she investigated the molecular pathogenesis of Borrelia burgdorferi. Prior to Molecular Biology, 3e, she contributed to the ancillary materials and online study guide for Molecular Biology's first two editions, as well as to the ancillaries for the companion book Biotechnology, also published by Elsevier. She is currently a biology professor at a college in Texas, where she teaches courses in anatomy & physiology and both majors and non-majors microbiology. She also challenges high school students in science competitions as the state biology contest director for the University Interscholastic League through The University of Texas at Austin. In her spare time, she enjoys hiking and camping with her loyal partner, a border collie named Ria.
