Jim Kerrigan works as a consultant for a computer hardware vendor. He has been involved with Fortran in both research and commercial environments for over twenty years. Jim admits to having used Fortran to create programs ranging from socioeconomic forecasting to data parallel algorithms and from a project management package to operating system monitors. Before working for computer companies (first Prime, then Sequent, and now Hewlett-Packard), Jim received a B.A. in archaeology from Temple University and an M.A. in regional science from the University of Pennsylvania.
