Thirteen UM Scientists And Engineers Named AAAS Fellows: Thirteen University of Michigan faculty members are among 539 newly elected fellows of the American Association for the Advancement of Science. Election as a fellow, a tradition that began in 1874, is an honor bestowed upon AAAS members by their peers. AAAS fellows are recognized for “scientifically or socially distinguished efforts to advance science or its applications.” The new University of Michigan AAAS Fellows are: Ruma Banerjee, Vincent Massey Collegiate Professor of Biological Chemistry and professor of biological chemistry, associate chair, Department of Biological Chemistry, Medical School. Recognized for fundamental studies of catalysis by vitamin B12-dependent enzymes and of trafficking and assimilation of vitamin B12 in humans; Kent Charles Berridge, James Olds Collegiate Professor of Psychology and Neuroscience and professor of psychology, College of Literature, Science, and the Arts. Recognized for significant contributions to the fields of psychology and neurobiology; for outstanding research on the neural mechanisms of emotion, motivation, learning and reward; Sally Camper, James V. Neel Collegiate Professor of Human Genetics, chair, Department of Human Genetics, professor of human genetics and professor of internal medicine, Medical School. Recognized for distinguished contributions to research into the molecular mechanisms of pituitary action and outstanding contributions to academic administration and education of biomedical scientists; Heather Carlson, professor of medicinal chemistry, College of Pharmacy, professor of chemistry, College of Literature, Science, and the Arts. Recognized for distinguished contributions to computational chemistry, particularly incorporating protein flexibility into structure-based drug design and the development and mining of protein-ligand databases; Christin Carter-Su, professor of molecular and integrative physiology, academic program director, Michigan Diabetes Research Center, Medical School. Recognized for distinguished scientific and administrative contributions to the field of endocrinology, particularly for delineating the cellular actions of growth hormone; Jun-Lin Guan, professor of internal medicine and professor of cell and developmental biology, Medical School. Recognized for distinguished contributions to the field of cancer biology and for services to professional societies to promote the careers of young scientists; Michael Imperiale, Arthur F. Thurnau Professor of Microbiology and Immunology, Medical School. Recognized for distinguished contributions to the field of virology, and to the discourse on responsible conduct of life science research; Paul Krebsbach, Roy H. Roberts Professor of Dentistry, professor of dentistry in the Department of Biologic & Materials Science, School of Dentistry, and professor of biomedical engineering, College of Engineering. Recognized for distinguished contributions to the cell and molecular biology of mineralized tissues with particular application to the restoration of congenital abnormalities and damaged tissues; John Laird, John L. Tishman Professor of Engineering and professor of electrical engineering and computer science, College of Engineering. Recognized for distinguished contributions to artificial intelligence and cognitive science, particularly through the sustained development and application of the Soar cognitive architecture; Malcolm Low, professor of molecular and integrative physiology and professor of internal medicine, Medical School. Recognized for distinguished contributions to the field of hypothalamic-pituitary disorders including pituitary adenomas and obesity, particularly using genetically modified mouse models; Martha Pollack, professor of information, School of Information, professor of electrical engineering and computer science, College of Engineering, vice provost for academic and budgetary affairs, Office of Provost, executive vice president for academic affairs. Recognized for distinguished contributions to artificial intelligence, specifically in computational models of rationality, discourse theory, temporal reasoning, and intelligent assistive technology, as well as for distinguished service to the field; Nils Walter, professor of chemistry, College of Literature, Science, and the Arts. Recognized for distinguished contributions to the field of biophysical chemistry, particularly by applying experimental and computational biophysical approaches to elucidate the function of non-protein coding RNAs; and Lois Weisman, Sarah Winans Newman Collegiate Professor in the Life Sciences, research professor, Life Sciences Institute, professor of cell and developmental biology, Medical School. Recognized for distinguished contributions to cell biology, particularly for advancing knowledge of how molecular motors attach to cargoes, and the roles and regulation of phosphoinositide lipids.
