sity. His major research interest is currently the preparation of artificial enzymes that can imitate the function of natural enzymes. His graduate students typically design a potential catalyst on the computer, synthesize it, and then determine its catalytic effectiveness and the mechanism involved. His lab also synthesizes molecules that mimic antibodies or biological receptor sites; they construct molecules that will bind to polypeptides with sequence selectivity in water, using mainly hydrophobic interactions. He has bachelor’s and PhD degrees in chemistry from Harvard University as well as a master’s in medical science, also from Harvard.

Arthur Ellis is Meloche-Bascom Professor of Chemistry at the University of Wisconsin at Madison. His research program focuses on materials chemistry, including the use of the photoluminescence of semiconductors to develop new classes of chemical sensors. He received the American Chemical Society’s George C. Pimentel Award in Chemical Education in 1997 and the Guggenheim Fellowship in 1989. He is the co-developer of modern instructional materials based on cutting-edge research, including texts, kits, demonstrations, and laboratory experiments. He also co-developed the Web site Innovations in SMET Education for the National Institute for Science Education. He co-organized a National Science Foundation workshop on the impact of technology on undergraduate mathematics and physical sciences. He served on the NRC Committee on Undergraduate Science Education from 1998 to 2000. He teaches chemistry at UW-Madison at the introductory, advanced undergraduate, and graduate level. He has a bachelor’s degree from California Institute of Technology and a PhD from Massachusetts Institute of Technology, both in chemistry.

Marc Loudon is Gustav E. Cwalina Distinguished Professor of Medicinal Chemistry and associate dean for research and graduate programs in the School of Pharmacy and Pharmaceutical Sciences at Purdue University. He specializes in teaching organic chemistry to prepharmacy students and in developing group-study techniques for the course. His research interests are in the area of bioorganic chemistry, with specific interests in the HIV protease, carboxy-terminal peptide degradation, and peptide synthesis. In 2000, Loudon was named Indiana Professor of the Year by the Carnegie Foundation for the Advancement of Teaching. In 1999 he received the Charles B. Murphy Award, the Purdue University-wide teaching award. He was twice selected for the Henry Heine Award for Outstanding Teacher in Purdue’s pharmacy school. Before coming to Purdue, he received the
