Frederick Bettelheim was a distinguished university research professor at Adelphi University and a visiting scientist at the National Eye Institute. He co-authored seven editions of INTRODUCTION TO GENERAL, ORGANIC, AND BIOCHEMISTRY and several Laboratory Manuals. He is also the author of EXPERIMENTAL PHYSICAL CHEMISTRY and co-author of numerous monographs and research articles. Professor Bettelheim received his Ph.D. from the University of California, Davis.
William H. Brown is emeritus professor of chemistry at Beloit College, where he was twice named Teacher of the Year. His teaching responsibilities include organic chemistry, advanced organic chemistry, and, more recently, special topics in pharmacology and drug synthesis. He received his Ph.D. from Columbia University under the direction of Gilbert Stork and did postdoctoral work at California Institute of Technology and the University of Arizona. He is a coauthor on INTRODUCTION TO GENERAL, ORGANIC AND BIOCHEMISTRY, 10e (Cengage Learning/Brooks Cole).
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 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 areas of interest include researching the physical chemistry of biomolecules, specifically, spectroscopic studies of protein-nucleic acid interactions. She is also coauthor with Shawn Farrell on BIOCHEMISTRY, 7e (Cengage Learning, Brooks/Cole).
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 taught biochemistry lecture and laboratory courses at Colorado State University for 16 years and now works for USCycling. 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 with Mary Campbell on BIOCHEMISTRY, 7e (Cengage Learning/Brooks Cole).
Omar Torres received his undergraduate degree in Chemistry from Texas A&M University in 1998 and his graduate degree in Inorganic Chemistry from UCLA in 2001. He has experience in teaching, research (inorganic, organic, and analytical) and academic administration. Professor Torres taught both inorganic and organic chemistry at UCLA, where he earned two UCLA Department of Chemistry Awards for Excellence in Teaching for the 1998-1999 and 1999-2000 school years. In addition, Professor Torres has worked at the Dow Chemical Company (Freeport, TX) in the area of Analytical Quality Control, developing and implementing new technologies for various plant operators and analytical scientists. He is currently Dean of Science at the College of the Canyons.
