Curriculum Vitae

Work Experience

Much of my work experience comes from personal interest in various fields. I have acquired much knowledge alone, and am autodidact in many areas as well as those in which I have formal training.

Semantic Web

Have followed the development of Semantic Web-technology since 1998. Have been involved in the following standardization processes in the World Wide Web Consortium:

Have also given comment to the development of the Simple Knowledge Organization System (SKOS).

Member Submissions to the W3C

These are early specifications that form the basis for further standardisation that is sent by the members of the World Wide Web Consortium:

Conference organization


Have written web pages with HTML since 1994 and CSS since 1997. Web Content Accessibility Guidelines are also important guidelines for my work.


2010-10-01 --
Ph.D. Research Fellow at Department of Informatics, University of Oslo.
2010-01-19 -- 2010-09-30
Developer at ABC Startsiden where I worked with modern Perl-based frameworks.
2007-08-01 -- 2010-01-31
Senior Knowledge Engineer at Computas AS, where I worked 100% with Semantic Web-technologies implemented on a Java-platform.
2006-12-01 -- 2007-06-29
Semantic Web Specialist for Opera Software. The position with Opera Software was divided 50/50, where half the position is "semantic web"-projects and standardisation.
2005-05-02 -- 2007-06-29
Information Systems Developer for Opera Software. Have participated in larger and smaller projects, first and foremost built applications on mod_perl2 and MySQL.
2002-05 -- 2005-05
Creating the web publishing framework for www.skepsis.no. This is a site I maintained on a voluntary basis since 1996. I have also had it as full-time employment in this period, working as a freelancer.
2004-04 -- 2004-06
Participation in the organisation of the events around the Transit of Venus 2004. Work tasks were similar to the solar eclipse, below.
2003-03 -- 2003-07
Participation in the organisation of the events around the Solar Eclipse 2003. Mainly, I created support systems and managed the distribution of 20 000 solar eclipse shades. This included creating a system to use so-called OCR data from Norwegian banks.
2003-02-28 -- 2003-05-21
Teaching course AST2110 - The Universe at the Institute of Theoretical Astrophysics, University of Oslo.
Minor Engagements


Free Software systems are preferred, that is, software which can be examined and understood to the core without any restrictions.

Have mainly developed on the Perl-platform, but also used Java in recent commercial projects projects. Focus has been on på Jena, Tomcat, Cocoon og Maven. Recently, the databaser-server Virtuoso has also been used.

Maintain an Internet server for personal purposes, known as pooh.kjernsmo.net running Debian GNU/Linux. Important subsystems include:

Have built, set up and maintain several desktop work stations, that are also running Debian GNU/Linux or Ubuntu Linux, with a recent version of KDE, OpenOffice and Emacs for editing. I tend to write documents in raw HTML or LaTeX.

I'm capable of using and superficially configure Microsoft products, but it is not a preferred way of working.

Authored Software

Authored scattered pieces of code in different software systems, and I have been acknowledge as a contributor to R. There are also some packaged modules, notably Perl Modules, where the most active projects are related to RDF. Some of them are also packaged in Debian. The largest is AxKit::App::TABOO which is now a dormant project.

Written two small PHP applications: a small webshop and a web frontend for Gamma Ray Burst Alert system.

Practical Science

Worked 3 times with the Nordic Optical Telescope. First as assistant for Dr. Andreas Jaunsen, and the two other times as primary observing astronomer in the Quoc Around-the-clock Collaboration. These times, my team was awarded 10 and 4 nights respectively.

Research assistant for Dr. Dagrun Vikhamar on several field excursions in the field of remote sensing.

Leisure Activities

Among my many interests is a long-standing participation in the sports of orienteering, ski-orienteering and cross-country skiing. Additionally, I have for many years enjoyed mountaineering, in various forms, at all times of the year. Most activities have in common that they require an enhanced situational awareness, management of potentially fatal risks and comprehension of abstract terrain models under time pressure and extreme physical and mental fatigue.
