the technical staff of the Microelectronics and Computer Technology Corporation
(MCC), Austin, TX, from 1985 to 1988. Since 1988, he has been with the Depart-
ment of Electrical and Computer Engineering at Mississippi State University, where
he is an Associate Professor. Courses that he teaches include Microprocessors, VLSI
systems, Digital System design, and senior design. His research interests include
self-timed digital systems and computer architecture.
J.W. Bruce received the B.S.E. fr.om the University of Alabama in Huntsville
in 1991, the M.S.E.E. from the Georgia Institute of Technology in 1993, and the
Ph.D. from the University of Nevada Las Vegas in 2000, all in electrical engineering.
Dr. Bruce has served as a member of the technical staff at the Mevatec Corporation
providing engineering support to the Marshall Space Flight Center Microgravity
Research Program. He also worked in the 3D Workstation Graphics Group at the
Integraph Corporation designing the world’s first OpenGL graphics accelerator for
the Windows operating system. Since 2000, Dr. Bruce has served in the Department
of Electrical and Computer Engineering at Mississippi State University. Dr. Bruce
has contributed to the research areas of data converter architecture design and
embedded systems design. His research has resulted in more than 30 technical pub-
lications and one book chapter.
Bryan A. Jones received the B.S.E.E. and M.S. degrees in electrical engineering
from Rice University, Houston, TX, in 1995 and 2002, respectively, and the Ph.D.
degree in electrical engineering from Clemson University, Clemson, SC, in 2005.
From 1996 to 2000, he was a Hardware Design Engineer for Compaq, specializing
in board layout for high-availability RAID controllers. He is currently an Assistant
Professor at Mississippi State University. His research interests include robotics,
real-time control-system implementation, rapid prototyping for real-time systems,
and modeling and analysis of mechatronic systems.
