The 2nd, 3rd, and 4th editions of this textbook all won a
TAA Texty Award from the Text and Academic Authors Association (in 2007, 2013, and 2015).
The "Textbook Excellence Award" recognizes works for their excellence in the
areas of content, presentation, appeal, and teachability.
Education
Ph.D., Computer Science,

Northwest Missouri State University
M.S.Ed., Mathematics, Northwest Missouri State University
B.S.Ed., Mathematics and English, Northwest Missouri State University
Teaching Interests
My teaching specializations are in the areas of computer security, database,
and operating systems. I am also interested in computer organization
and architecture. I enjoy teaching beginning programming classes.
Research
My main research interests are in object-oriented database systems
and security, operating systems security and concurrency control,
the active learning paradigm, and total quality management in the
classroom. I developed a multilevel security model for
object-oriented database systems and have investigated
object-oriented querying and transaction concurrency. I
have also done some auguring of the Internet.

One of my current research goals is to find collaborators a
bit closer to home. If what I'm doing looks interesting, get in touch.
