My academic degree is a Fil Kand in Computer Science, Mathematics and
Logic from Stockholm University. I am a Ph.D. student in Computer
Systems at the Royal Institute of Technology. (I have also studied
medicine for a few years in the seventies at the Karolinska Institute
where I got interested in programming computers). An early
program (coauthored in BASIC by Stig
Svensson, Ph.D. in linguistics and med school colleague) generated a
reasonable subset of grammatically correct swedish sentences and
showed me the awkwardness of imperative languages for many complex
tasks. The program was first (1976) implemented on a NORD-10 time-sharing
machine at Karolinska Institutet. In 1980 I ported the program to an
ABC-80 computer after a request to exhibit the program on Tekniska Museet
at the exhibition "Hej Dator!" the same year. Around 1990 I implemented a
basic interpreter and some other tools for the purpose of experimenting with
analysis of imperative programs for the purpose of transforming control
structures into a more readable, but operationally equivalent, form.
The sentence-generator, slightly modified was a good test example. The

some output are
(Copy this directory and run the make file).
Other early programming experiences were in
tools for music production,
signal processing and lab equipment.
I have worked with courses in logic programming, program
analysis, networking and AI. Most of the research projects I have worked in
have been related to
implementation of communication protocols
and with technology for logic programming languages. During the period 1990-1991 I was project manager for the
SICStus Prolog project supported by Ericsson and CelsiusTech. From 1992-1996 I worked in the ESPRIT project
ParForce, where a program for analysis of programs written in the
During 1993-1996 I also served as an assistant project coordinator and project manager for the ESPRIT project
ACCLAIM, a "sister" of ParForce.
I have participated as a program committé member in the PACLP conference (and its predecessors PAPPACT and PAP).
I have been a referee in a number of conferences and journals. Also ICLP, ISLP, NACLP, FGCS and JLP have used my services.
From 1996 until late 1998 I participated in projects on distributed tactical surveillance, and I have then worked mainly with decision support for distributed planning and scheduling. I represented SICS and "swedish industry" in the European Union network COMPULOG.
From 2002 until august 2005 my SICS activities were mainly the administrative coordination of the EU-project PEPITO. I currently work as the head of unit SCS Software and Computer Systems, and lecturer at the of ICT/KTH (the school of ICT in the Royal Institute of Technology), Stockholm, Sweden.
I pursue an as yet unfinished thesis on analysis techniques for a concurrent constraint logic programming language. The activity has been rather slow paced, in fact from 2002-2007 there has been practically no time (money) available to work on this, but the plan to finish it is still there!
