Personal Profile:
Professor, Univ of Florida. Member of the SIAM Council ( http://www.siam.org/about/board.php ). Author/co-author of many built-in sparse functions in MATLAB: [L,U,P,Q] = lu (A) when A is sparse (UMFPACK), L=chol(A) (CHOLMOD), x=A\b when A is sparse and square, COLAMD, SYMAMD, AMD, ETREE, DMPERM, SYMBFACT, and sparse matrix multiply (sparse-times-sparse and sparse-times-dense). See also http://www.cise.ufl.edu/~davis . Much of this work is discussed in my book "Direct Methods for Sparse Linear Systems", SIAM, Sept. 2006, which presents the theory and practice of sparse matrix algorithms, and discusses how MATLAB performs its sparse matrix computations. Additional features, latest versions, and better performance for sparse matrix operations in MATLAB can be obtained from my files posted on MATLAB Central.

Professional Interests:
numerical linear algebra, sparse matrix algorithms, computational science, mathematical poetry
