Craig Steffen at the NCSA

Craig Steffen is a senior research scientist at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. He has been part of the Science and Engineering Applications Support (SEAS) team in the Blue Waters project since 2012.

Craig joined the NCSA in July 2002, and mostly telecommutes from his home in southeastern Kentucky. He works normal working hours (eastern time), and can be reached via e-mail, work phone 217-300-1881 or his mobile 217-979-2392.

Craig is in the NCSA building (office 4006G) once a month for a few days, usually Monday through Thursday early afternoon. His schedule for these visits is available on an internal wiki page.
