This volume provides researchers with recent information on bioactivation reactions of drugs and toxicants. It also provides examples of how molecular and genomic biology, proteomics, mass spectrometry, and computational modeling are used in bioactivation research. In other sections, focus is on recent applications of bioactivation research in pharmacology, toxicology, and environmental health sciences, where contributors demonstrate the integration of bioactivation research.

Dr. Elfarra received his B.S. degree in Pharmacy at Cairo University, Cairo, Egypt, in 1975 and his Ph.D. degree in Medicinal Chemistry at the University of Minnesota, Minneapolis, MN, in 1983. In 1985, Dr. Elfarra joined Shell Development Company in Houston, Texas as an associate research toxicologist after he completed his postdoctoral training in Pharmacology at the University of Rochester in Rochester, NY. Dr. Elfarra joined the University of Wisconsin-Madison as assistant professor in 1986. He was promoted to associate and full professor in 1992 and 1996, respectively. He served as the chair of the campus Biosafety Committee and has trained a large number of undergraduate students, graduate students, and postdoctoral students in his laboratory. He is the current director of the institutional training grant from NIEHS. Dr. Elfarra has served on the executive committee for the Division of Toxicology of the American Society for Pharmacology and Experimental Therapeutics, and has organized and participated in many national and international symposia focused on topics related to his research. He has served as consultant for many organizations, such as NIH, the National Research Council Board on Environmental Studies and Toxicology, the Health Effects Institute, Health Canada, and the International Agency for Research on Cancer.

Zusammenfassung
I have always been interested in chemistry and biology. My undergraduate, graduate, and postdoctoral trainings in pharmacy, medicinal chemistry and pharmacology, respectively, have strengthened this interest and led me to realize that significant advances in medicine have frequently been realized because of research at the chem- trybiology interface. I am hoping that this comprehensive volume on recent advances in bioactivation research will stimulate pharmacologists, medicinal chemists, phar- ceutical scientists, and graduate students in these fields and related areas to consider and use bioactivation research when they explore and chart new frontiers in drug design and drug development and when they consider ways to reduce the side effects of existing drugs by making prodrugs. As for the toxicologists and environmental health scientists, I hope this volume will help them generate the knowledge needed to understand better mechanisms of toxicity to improve human risk assessments and intervention methods after occupational or environmental exposure to various hazardous chemicals.
