CV
Walter D. Neumann joined the faculty of Barnard in January 2000, having previously held a Personal Chair at the University of Melbourne, Australia. He has had continuous research funding since 1976 from the National Science Foundation and the Australian Research Council, resulting in over 120 research articles and monographs in geometry, topology, and group theory. He is managing editor of Geometry & Topology, the leading journal in its field, is on the editorial boards of several other research journals, and is a member of the board of directors of the nonprofit Mathematical Sciences Publishers (Berkeley). He is on the Human Rights Committee of the New York Academy of Sciences; in 2002 he was elected to the European Academy of Sciences.
Professor Neumann's teaching specialties include combinatorics, modern algebra, algebraic topology and modern analysis.
