About Myself
|
Senior Computer Scientist at the
Artificial Intelligence Center of SRI International
in Menlo Park, California. More than 25 years
in AI: knowledge representation and reasoning, planning, dialogue
systems, machine learning, and large language models.
My main interest today is neuro-symbolic systems - combining logic-based knowledge representation and reasoning with LLMs and deep learning. At SRI since 2010, in more than ten projects: mainly the AURA intelligent textbook, where I maintained and scaled the knowledge representation and reasoning backend; lead developer of the ontology-based dialogue system OntoVPA; and, more recently, LLM-based knowledge management. More on the research page. 2004 to 2013: co-founder, developer and consultant of Racer Systems, the company behind the OWL / description logic reasoner RacerPro. I created its query language nRQL and its IDE RacerPorter. Racer is now open source. Dr. rer. nat. in computer science, Hamburg University of Technology (2008): dissertation on software architectures for ontology-based information systems (in German; English summary). Diplom in computer science, University of Hamburg (1998): VISCO, a visual language for spatial queries; before that, GenEd, a generic graphics editor in Common Lisp. Outside of work: hardware tinkering and retro computing. I design and build expansion hardware and emulators for the home computers I grew up with - one project was a winner of the Hackaday Reinvented Retro contest in 2021. See the hardware and software pages, Github and Hackaday.io. |

About These Pages
These pages were generated with a little "do it yourself" content management system in Common Lisp. The pages are hosted on a Raspberry Pi 4. The CMS features a proprietary non-XML markup language. Documents are instances of (CLOS) document classes for which (CLOS) presentation methods can be specified (for example, blog entries are presented differently from galleries).
The macros date from 2008 and were last changed by hand in 2017. Since October 2026, Claude Code maintains and updates this site - using the same stone-age macros. So much for the stability of Common Lisp code, and the maintainability of its abstractions :-) The history of these pages.
