About pngwen

I am a professor of computer science at the University of Tennessee at Martin. I conduct research in artificial intelligence and computer science education. I dabble in theory of computation and programming language development.

I have been coding ever since I wrote my first line of BASIC back in the 1980s. I like retrocomputing, modern computing, artificial intlligence, programming, electronics, and math. I generally spend my time coding and reading pretty much anything I can get my hands on.
