I have been teaching Computer Science and Information Systems courses for the University System of Georgia for the past six years. I have been a radio D.J., a Database Administrator, and a Translator at various points in my previous working life.

I'm an active member of the IEEE Computer Society, the ACM, and SIGGRAPH, the ACM's Special Interest Group for Graphics. I am also an active member and the Webmaster for the Georgia Council of Teachers of Mathematics (see some of my work at http://www.gctm.org ).

I enjoy creating 3D animations, programming, investing, foreign languages (5 so far), reading, boating and the outdoors. To see a short example of my 3D animation work, please click here.

I have a Ph.D. in Computer Science from Georgia State University, an M.Ed. and a B.S. in Mathematics from North Georgia College & State University. You can see some of my recent publications and presentations below.

For the past eight years, I have traveled annually to South America on 1-2 week mission trips. This year we're taking a team of 10 doctors and nurses to a remote Andean village. To see photos of prior trips to Ecuador go to http://www.dbch.org/ecuador03 or Ecuador 2002.
