Professional Experience


January 2000 - Present: Senior Research Scientist. Norwegian Computing Center,
                          Department of Applied Research in Information Technology (DART), Oslo, Norway.

My past and present research areas encompass:


February 1998 - December 1999: Research Scientist. Telenor, Research and Development Dept.,
                                                        Security Group, Kjeller, Norway.

I conducted research on the security aspects of distributed object computing systems, including object middleware (with special emphasis on CORBA security and CORBA firewall security), mobile communications and Internet. I have also worked on risk analysis and security policy related issues.

I proposed the basic idea in which the successful CORAS (A Platform for Risk Analysis of Security-critical Systems) proposal within the 5th EU/IST framework was based. Its main objective is to develop a practical framework for a precise, unambiguous and efficient risk analysis, by exploiting the synthesis of risk analysis methods with object oriented modelling, semiformal methods and tools, in order to improve the security analysis and security policy implementation of security-critical systems.


August 1997 - January 1998: Senior Engineer. Telenor, Research and Development Dept., Oslo, Norway.

I was with the KOF/Architecture Group, where I worked on the FLEKSIT Project, and was one of the five sub-project managers. The purpose of the FLEKSIT project was to evaluate different types of middleware and security issues related to them, and to make recommendations as to which type of middleware Telenor should adopt as its standard integration technology, and how it should be used.


April 1996 - July 1997: Software Development Engineer.  Alcatel Telecom Norway A/S, Division Telnet,
                                       Oslo, Norway.

My work consisted of modelling, designing and implementating the ALMA CCB (Customer Care and Billing) system based on Systemator IV, Sysdul, ORACLE, and UNIX environments.


April 1994 - January 1996: Researcher/Software Development Engineer. ABB Corporate Research, SW Group and
                                              NERA AS Division Satcom, SW Group, Billingstad, Norway

I worked on ABB NERA's Race project - SCORE (Service Creation in an Object-Oriented Reuse Environment)- and ABB Tralfa's robot system, and modelling, developing and maintaining control programmes and software development tools for the LES (Land Earth Station) Channel Unit (CU) subsystem of NERA's satcom, which involved among other things:


January 1991- June 1993: Scientific Fellow. CERN PS/PO /CO, Geneva, Switzerland.

My work consisted of developing software for the control and monitoring of the particle accelerators in distributed and complex environments.
January 1989 - December 1990: Scientific Associate. CERN/DELPHI (Geneva, Switzerland) with home
                        institutes Department of Physics, University of Oslo, and NAVF (now NFR), Norway
During where I was responsible for the implementation of the control system for the DELPHI-SAT detector built by the Norwegian Group (Departments of Physics at University of Oslo & University of Bergen), and the integration of this control system into the DELPHI Slow Controls system as a whole. I also participated in the development of the data acquisition system for the DELPHI-SAT.
