Activities at the Geometry Center

Dick has been a participant in Center activities since its inception in 1991. He led a project on visualization of invariant sets in four dimensions during the academic year 1991-92, and he organized a workshop on invariant sets for symplectic maps in 1992. In May 1993 he was appointed to the Center faculty. He became Interim Director in February 1994 and was appointed Director in June 1994. As Director, he is responsible for the overall management of Center activities and for implementing and maintaining the supervisory, budgetary, and accounting systems necessary for the Center to carry out its mission and its programs. He works with the Board of Governors to set the scientific, technological, and educational directions for the Center.


Dick has been at the University of Minnesota since 1970, when he joined the School of Mathematics as an assistant professor. He worked his way through the ranks, eventually becoming a professor in 1979. He served as department head from 1986 to 1990. His research area is dynamical systems, with particular emphasis on classical mechanics. He has held visiting positions at the Courant Institute, the University of Wisconsin, the Swiss Federal Polytechnical Institute, the Mittag-Leffler Institute, the Institute for Pure and Applied Mathematics in Rio de Janeiro, the Unversity of Colorado, and the University of Paris. He has been active in health care issues, serving as Chair of the University Senate Health Plan Subcommittee.
