Mary K. Campbell is Professor Emeritus of Chemistry at Mount Holyoke College, where she taught biochemistry, general chemistry, and physical chemistry as well as advised undergraduates working on biochemical research projects. Her avid interest in writing led to the publication of the first of many highly successful editions of this textbook. Originally from Philadelphia, Dr. Campbell received her Ph.D. from Indiana University and completed postdoctoral work in biophysical chemistry at Johns Hopkins University. Her area of interest includes researching the physical chemistry of biomolecules, specifically, spectroscopic studies of proteinnucleic acid interactions.
Shawn O. Farrell, a native of Northern California, received his B.S. in Biochemistry from University of California, Davis, studying carbohydrate metabolism. He completed his Ph.D. in Biochemistry at Michigan State University, where he focused on the study of fatty acid metabolism. Dr. Farrell became interested in biochemistry while in college, as it was relevant to his passion for bicycle racing. He raced competitively for 15 years and now officiates bicycle races worldwide. He has worked at Colorado State University for the last 16 years, teaching undergraduate biochemistry lecture and laboratory courses. Professor Farrell has written scientific journal articles about specific research projects and about laboratory teaching, as well as articles for sports publications, such as SALMON, TROUT AND STEELHEADER magazine. He is co-author of this highly successful biochemistry text.
