Dr. Mark Fahey
Dr. Mark R. Fahey is presently Research & Development Staff in the Scientific Computing Group within the National Center for Computational Sciences (NCCS) at ORNL. He has been integration techniques with demonstrated applicability to problems in chemistry and physics. the primary NCCS liaison for the fusion researchers funded by the DOE; and as such, has ported and/or optimized several of the DOE Fusion codes (AORSA, GYRO, NIMROD, and M3D) on NCCS computers, which include a Cray X1E, Cray XT3, SGI Altix, and an IBM Power4. He was from 2001-2003 a Research Scientist as part of the Joint Institute for Computational Science at ORNL. Prior to joining ORNL, Dr. Fahey was a Research Scientist at the Engineering Research and Development Center in Vicksburg, MS from 1998 to 2001. There he was part of the Computational Migration Group (CMG) and later became the Director of the CMG.
Dr. Fahey received his B.A. from St. Norbert College in 1992 and his Ph.D. from the University of Kentucky in 1999. His research at the University of Kentucky in scientific computing and numerical linear algebra covered topics such as sparse and dense matrix computations, eigenvalue problems, iterative solvers, probability theory, bilinear forms, and numerical
