Leadership Team

Doug Lenat

Dr. Douglas B. Lenat is one of the world’s leading computer scientists, and is the founder of the Cyc project and CEO of Cycorp.

Dr. Lenat has been a Professor of Computer Science at Carnegie-Mellon University and Stanford University and has received numerous honors including:

  • Awarded the bi-annual IJCAI Computers and Thought Award which is the highest honor in Artificial Intelligence;
  • Named the first Fellow of the AAAI, the Association for the Advancement of Artificial Intelligence.
  • Fellow of the American Academy for the Advancement of Science (AAAS)
  • Fellow of the Cognitive Science Society

His best-known published books include:

  • Knowledge Based Systems in Artificial Intelligence (1982, McGraw-Hill)
  • Building Expert Systems (1983, Addison-Wesley)
  • Building Large Knowledge Based Systems (1989, Addison-Wesley)

He has authored over one hundred publications primarily in the areas of machine learning, automatic program synthesis, knowledge based systems, representation, automated inference, and he is an editor of the J. Automated Reasoning, J. Learning Sciences, J. Applied Ontology, J. Applied Artificial Intelligence, and the Springer Artificial Intelligence series of books. His Stanford thesis earned him the bi-annual IJCAI Computers and Thought Award in 1977.

Dr. Lenat received his PhD in Computer Science from Stanford, investigating automated discovery based on “interestingness” heuristics, for which he received the  bi-annual IJCAI Computers and Thought Award, and in 1980 he was one of the co-founders of AAAI and of Teknowledge. Besides professoring at CMU and Stanford, he was Principal Scientist at MCC, where he founded the Cyc Project in 1984 – something he dubbed “ontological engineering”.  At the end of 1994, the Cyc project spun out of MCC, becoming Cycorp, Inc., and he has served as its CEO since that time.  Dr. Lenat is a founder and Advisory Board member of TTI Vanguard, where he continues to co-run four conferences each year, and he holds the distinction of being the only individual to have served on the Scientific Advisory Board of both Microsoft and Apple.


Stephen Garrisonstephen

Stephen Garrison is President of Cycorp.  He brings strategic and operational experience from both the public and private sectors.

At the White House, he served as Special Assistant to the President for Domestic Policy under President George W. Bush.  During his time in the West Wing, he focused on a range of domestic policy issues.  Earlier, he also served on President Bush’s Presidential Campaign policy staff and as Deputy Director of Rapid Response as well as on the policy staff of then-Governor George W. Bush.

While at Bain and Company as a Principal, he served clients across industries, launched a new regional industry practice and was a member of the Performance Improvement practice area.  Later, after starting a hospital management company and serving as its CEO, he led a successful hospital turnaround and strategic transaction as CEO of the hospital and General Partner of the 83 member ownership group.  Garrison was also previously named one of Becker’s Hospital Review national 25 Rising Stars Under 40 in Healthcare.

Immediately before joining the Cyc team, he served as CEO of Cooper Wellness Strategies, the corporate and technology affiliate of the world-renowned Cooper Clinic.

Stephen has a BA from Stanford University in Public Policy and an MBA from the Harvard Business School.


Keith Goolsbey
Chief System Architect and Inference Engine Programmerkeith

Keith Goolsbey is currently the chief software architect and inference engine programmer of the Cyc system, and is a Senior Member of the Technical Staff. He holds a B.S. in Electrical Engineering and an M.S. in Computer Science, both from the University of Texas at Austin. The focus of his M.S. studies was artificial intelligence and expert systems. In 1990 he joined the Cyc Project at Microelectronics and Computer Technology Corporation (MCC), where he worked to expand the nascent Cyc ontology. Beginning in 1993, he took responsibility for the development of the SubL environment which forms the run-time foundation for all deployed versions of the Cyc system. In 1995 Keith became a founding member of Cycorp, Inc. At this time he took responsibility for the design and implementation of several additional portions of the Cyc technology, including the storage of the knowledge base, the inference engine, and HTML-based interfaces. Additionally, Keith designed and implemented the prototype for Cycorp’s current Semantic Knowledge Source Integration (SKSI) system, which enables the Cyc to reason with content from databases as if it were part of the knowledge base. He has recently completed managing Cycorp’s efforts for DARPA’s Architectures for Cognitive Information Processing (ACIP) program, and is currently managing the DTO Efficient Pathfinding project.

Some of his publications include:

Ramachandran, D., Reagan, P. and Goolsbey, K. “First-Orderized ResearchCyc: Expressivity and Efficiency in a Common-Sense Ontology.” In Papers from the AAAI Workshop on Contexts and Ontologies: Theory, Practice and Applications. Pittsburgh, Pennsylvania, July 2005.
