I managed teams in the late 1980s and early 1990s doing artificial intelligence research and products at HP.  

During this time my teams and I worked on:

- Frame base reasoning tools/research

- AI applications

- REDUCE (a mathematics tool)

- Expert systems and tools

- Common LISP development environments

In addition to the work efforts, I also did some work on a public domain LISP language called XLISP:

- XLISP 2.0 Language Reference (Dec 11, 1989, in the public domain, also available in web format)

- XLISP 2.0 Objects Primer (Feb 3, 1990, in the public domain)
