My work is made possible by continuing support from
the National Science foundation through a CAREER Award from the
Division of Mathematical Sciences (DMS) and through the Materials
Research in Science and Engineering Center at the University of
Chicago that is funded by the Division of Materials Research (DMR). In
the past, my work was supported by research grants from the NSF, the
Alfred P. Sloan Jr. foundation (1999-2003) and the Office of Naval
Research (1995-1996).
