The Qx-coder - Author bios

by M. J. Slattery and J. L. Mitchell

Biographical sketches of authors

Michael J. Slattery IBM Microelectronics Division, Burlington facility, Essex Junction, Vermont 05452 (mslatter@us.ibm.com). Mr. Slattery graduated from the University of Notre Dame with a B.S. degree in electrical and computer engineering. He joined the IBM Microelectronics Division in 1990 and has worked in VLSI failure analysis, polyimide films and via process engineering, encryption product design, adaptive and lossless data compression product design, arithmetic coding for VLSI implementations, and 2D graphical acceleration.

Joan L. Mitchell IBM Research Division, Thomas J. Watson Research Center, P.O. Box 218, Yorktown Heights, New York 10598 (joanm@us.ibm.com). Dr. Mitchell graduated from Stanford University with a B.S. degree in physics in 1969. She received her M.S. and Ph.D. degrees in physics from the University of Illinois at Champaign-Urbana in 1971 and 1974, respectively, joining the Exploratory Printing Technologies group at the IBM Thomas J. Watson Research Center immediately after completing her Ph.D. She was a manager at the Research Center for nine years, worked for three years in IBM Marketing, and returned to the IBM Research Division in 1991 to work again in the Image Technologies group. In 1994, she left for a two-year leave of absence. During her leave, Dr. Mitchell co-authored a book on MPEG, consulted for IBM Burlington, and was a visiting professor at the University of Illinois for six months. Back at the IBM Thomas J. Watson Research Center, she is now a Research Staff Member in the Image Applications Department. Since 1976 Dr. Mitchell has worked in the field of image processing and data compression. She received IBM Outstanding Innovation Awards for two-dimensional data compression in 1978, for teleconferencing in 1982, for the image view facility in 1985, for resistive ribbon thermal transfer printing technology in 1985, for speed-optimized software implementations of image compression algorithms in 1991, and for the Q-coder in 1991. She is a member of APS, IEEE, Sigma Xi, and IS&T and is a co-inventor on 30 patents.
