Artificial Intelligence and its applications, especially knowledge representation, planning, natural language, and machine learning. I have also worked in artificial neural networks, image processing, and document management.
Languages and programming environments for evolutionary development of complex software systems, especially languages of the Lisp family.

N. E. Berg Company,
Summers 1965-1972: Summer jobs while at
M.I.T. were at Honeywell Computer Science Center, Digital Equipment
Developed the BUILD program (Master's thesis at MIT), one of the first planning programs to implement plan modification and failure-directed backtracking.
Developed the NETL knowledge representation system (Ph.D. thesis at MIT), which stored real-world, common-sense knowledge in a massively parallel network of simple hardware elements and links. This "data-parallel" approach made it possible to perform human-like inference and retrieval tasks very quickly and flexibly. NETL was a precursor of data-parallel computers (as in the Connection Machine) and "connectionist" approaches to Artificial Intelligence.
Member of the 5-person core design team for the Common Lisp programming language. Moderator for internet-based design discussions involving dozens of major contributors.
Head of the CMU Common Lisp project that produced a widely used free implementation of Common Lisp. At its peak, CMU CL was used by at least 10 companies as the basis for their own Common Lisp implementations. The CMU CL compiler set a new standard of performance for languages of the Lisp family.
Developed a number of learning algorithms for artificial neural networks, including Quickprop, Cascade-Correlation, and Recurrent Cascade-Correlation. These algorithms typically learn desired behaviors10 to 100 times faster than older algorithms.
Principal Investigator for the "Automated Interactive Microscope" (AIM) project, whose goal was to couple high-performance computing to advanced light microscopes for real-time processing of biomedical images.
Head of the Gwydion Project at Carnegie Mellon. This project worked with Apple Computer to define the Dylan programming language and developed two public-domain implementations of Dylan. We also developed an advanced software development environment for the Java language.
As President and CTO of Just Research, created a well-regarded computer science research lab near the Carnegie Mellon campus. In 2 years, built up the lab from initial conception to 25 full-time researchers.
Overall manager and system
architect during the first phase of the RADAR Project in Carnegie Mellon’s
Developed the Scone Knowledge-Base system, based in part on ideas from my earlier NETL work, but optimized to run well on standard high-end workstations.
Fellow of the American Association for Artificial Intelligence (AAAI).
