My formal Ph.D. assignment is at the School of Informatics, at the University of Skövde, Sweden.
I am currently on leave of absence from my position at the Swedish Armed Forces Head Quarters, where I hold the rank of Captain (Air Force). During this time I am employed by the Swedish Defence University (SEDU), where my research is funded under the Swedish Armed Forces Joint Program for Doctoral Studies.
My main supervisor is professor Martin Norsell, professor of Military Technology at SEDU in Stockholm.
I graduated from the Commissioned Officer Program at the Military Academy of Östersund in 2001, and received my M.Sc. degree in Computer Science and Engineering from Linköping University in 2007.
My main field of research lies within the academic subject of Military Technology. At the Swedish Defence University (SEDU), the subject is defined in the following way:
“Military technology is the science which describes and explains how technology influences military activity at all levels and how the profession of an officer affects and is affected by technology. Military technology is based on several different subject areas from different disciplines and combines understanding of the military profession deriving from social science with the foundations of natural science and with a superstructure and dynamics supplied by engineering.” (Axberg, 2006)As can be understood by the definition above, the subject of Military Technology, as perceived at the SEDU is, heavily interdisciplinary and deals with broad ranges of research questions revolving around technology and its relation to the military profession. In order to benefit from expertise within traditional disciplines, Ph.D. students at the SEDU commonly have subject co-supervisors at external high-ranking universities. My main collaboration has thus been with RTSLAB at Linköping University.
More in detail, my research is mainly focused on studying operative applications of Information and Communication Technology (ICT). One of the greatest research challenges in this area is finding methods where advanced communication technology can be used for inter-organizational collaboration, to share information and resources of mutual interest, while simultaneously safeguarding highly valuable, possibly classified information, also residing in the systems. Failure to achieve any of these goals will inevitably preclude effective use of any proposed platform, due either to lack of trust in overall system security or due to inefficiency as a result of extensive system limitations or complexity.
Another challenging research task within this area is designing military-grade ICT systems which, on the one hand are effective and secure, but on the other hand also provide ethically sound mechanisms for information management. Privacy issues have recently become a political hot topic across Europe, sparked by both common EU legislation, such as the IPRED EU directive, and national initiatives, such as the Swedish “FRA” signals intelligence law. Thus, finding solutions which are able to uphold user privacy during peacetime scenarios, while allowing for fully efficient operation during conflicts or warlike peace-enforcement operations, is subsequently becoming increasingly desirable.
During 2008-2010 I took part in an interdisciplinary research project called Hastily Formed Networks with Heterogeneous Users, financed by the Swedish Civil Contingencies Agency (MSB). The project studied the issues associated with multi-organizational collaboration in post-disaster emergency response scenarios, where the involved stakeholders have heterogeneous backgrounds. We try to identify the necessary conditions for ensuring effective, pervasive and sustainable information exchange within and between organizations participating in hastily formed networks. The project also studied several aspects of critical information infrastructure protection (CIIP), such as achieving security and reliability in disasters. The project report can be downloaded here: [PDF]
During 2010-2011 I focused on studying security solutions for military-grade mobile ad-hoc networks (MANETs). I used the Common Tactical Radio System (GTRS) as a baseline, which is a MANET-based communications platform being developed by the Swedish Armed Forces and the Swedish Defence Materiel Administration (FMV). I investigated the conditions for implementing a mechanism for anomaly detection, based on algorithms and protocols previously developed at RTSLAB. The results are presented in the paper “Best-Effort Data Leakage Prevention in Inter-Organizational Tactical MANETs” found below.
