published papers, books, edited books, lecture notes and reports.
The biographical notes then refer to this list.

For many years I was not too fond of photos of myself.
That changed around my age of 60!
Some Guiding Principles
Computer & Computing Science
I consider myself a computing scientist primarily interested in
I understand the study and
of the "things" that can "exist inside" computing
devices (i.e., data and computations) -
and the study and
knowledge of computing devices.
I understand the study and
of how to construct "those things", i.e.,
I consider myself to have primarily contributed to the area of formal

domain science & engineering
My main focus, since 1977, has been on the development of "large"
compilers (like for CHILL and Ada),
and human artifact infrastructure software
(for pipelines, railways, health
care, banking, road traffic, container terminal ports, etc.).
A recent focus since 2017, has been on
Are We Teaching & Researching the Right Things?
An Essay on Didactics
indicate a rather different approach to
software engineering than is
currently en vogue.
- Instead of starting with coding programs, studying and teaching
- [5,12] suggests that we start with studying the
research its wider implications, describing
varieties of subsets;
-  then proceed by analysing and
based on a suitably delineated domain
- [64,65,66] finally developing the
code as outline in these three text books.
- As it is today nobody takes domain science & engineering
- Think of that.
- Think of civil engineering, mechanical engineering, electrical
enginering and chemical engineering
proceeding on a basis of there being no scientifc physics and
- We are doing it all the wrong way around!
- We have to reorganise our university curricula.
- We have to reorganise our research agendas,
