By Andrea Lynn Two UI faculty members were appointed professors in the university's Center for Advanced Study by the UI Board of Trustees at its meeting last week in Rockford, Ill. The new CAS professors are May R. Berenbaum, entomology, and Jiri Jonas, chemistry. Their appointments are effective Aug. 21. Professors in the center are permanent members of the center community, chosen for their outstanding scholarship. Appointment to a professorship in the center is the highest recognition that the campus can bestow on a member of its faculty. The scholars were recommended for appointment to the center by Chancellor Aiken, upon recommendation by the dean of the Graduate College and vice chancellor for research in consultation with the director of the Center for Advanced Study. Berenbaum is a major figure in her field, the interaction and co-evolution of insects and their plant hosts. As such, she calls on expertise in entomology, botany, ecology, evolution and chemistry. Her works are viewed by her peers to be of the highest quality, and often are trend setting. For her pioneering studies, she was elected to the National Academy of Sciences in 1994 at the age of 40. At Illinois, Berenbaum also has distinguished herself as an outstanding teacher of undergraduate and graduate students, as a campus leader and administrator, and as an enthusiastic popular writer and speaker. She has been head of the UI entomology department since 1992. She was named a University Scholar in 1985, and a Jubilee Professor in 1993. Jonas is a pioneer in the use of high-pressure nuclear magnetic resonance and Raman spectroscopy to study structure and dynamics in liquids, modern theories of reaction rates in liquids, the behavior of molecules in confined geometries such as porous solids, and the changes of protein conformation with pressure. The impact of his work covers the vast area from pure chemical physics through materials science to molecular chemistry. Jonas received the first Joel Hildebrand Award for the study of the liquid state, and was elected to the National Academy of Sciences and the American Academy of Arts and Sciences. In addition to his outstanding and active career as a research scientist, Jonas has made important contributions to the campus as director of the School of Chemical Sciences (1983-1993) and as director of the Beckman Institute for Advanced Science and Technology since 1993.
