Research interests

Starting as a theoretical physicist, I now work within computing disciplines. I like elegant or creative ideas that one strives to work into a scientific discipline.

Ongoing and unfinished projects

A route to `intelligence' at the system level

Further developments of promise theory:

The main theme of my work, since 1998 has been the understanding and scaling of human-computer systems, in particular the idea of self-maintaining, `smart' functional infrastructure, using embedded information technology. Since 2007, I have been working on two main subjects: the formalization of the concepts and applications of Promise Theory (largely with Jan Bergstra) and the question of Knowledge Management for IT infrasructure, particularly semantic networks. This is in continuation of previous work on the dynamics and semantics of information infrastructure for pervasive computing or "Internet of Things".

In the overlap between Promises and Knowledge, I got interested in BDIM "Business Driven IT Management", or what it means to make IT business relevant (thanks for Claudio Bartolini). Following talks by Claudio, Jacques Sauve and John Wilkes in 2006, I drafted this sketch (DOI: 10.13140/RG.2.1.1080.0800) was used as an outline of a keynote held at NOMS in Brasil in 2008, which was the start of using Promise Theory to describe this business alignment, and later DevOps.


"There is nothing more difficult to take in hand, more perilous to conduct or more uncertain of its success than to take the lead in the introduction of a new order of things, because the innnovator has for enemies all those who have done well under the old scheme and lukewarm defenders in those who may do well under the new..."
(Machiavelli, The Prince)

"Perhaps the greatest discovery of all this research is that we no longer can separate basic from applied science The disciplines are connected in ways they have never been before..."
(Vice President Al Gore)

"There is no use in looking to scientific `papers', for they do not merely conceal but actively misrepresent the reasoning which goes into the work they describe."
