Biography

I work as a research director in the field of cybersecurity at the Faculty of IT at the University of Jyväskylä. My research areas are critical infrastructure protection, cybersecurity education and cyber warfare. I have previously served for 30 years in the Air Force in the fields of intelligence, surveillance and control&command. I am also a adjunct professor in air and cyber warfare at the National Defence University. I have worked for years as an expert in committees of the Finnish Parliament.

I have over 250 publications, research reports and articles on C4ISR systems, cyber security and defence, information warfare, air warfare and defence policy. I have served as the editor-in-chief of a Military magazine from 2001 to 2026.

My current tasks are related to the management of national and international research projects and I also have doctoral researchers to supervise. The projects deal with cybersecurity training in the Finnish university sector, protecting the submarine cable and pipeline network, and developing a cyber situational picture, especially from an early warning perspective. I am conducting research collaborations with the University of Houston and Texas A&M University.

Research interests

The quantity and value of digital information has increased so also the attacks of criminals and other malicious actors have increased. Of primary concern is the threat of cyber-attacks against to nations critical infrastructures, functions vital to society, economy, or national security. Cyber security touches everybody.

One of my research focuses on cybersecurity education in Finnish universities (9) and how this network can be developed. We are currently specifically exploring opportunities for continuing education.

The European submarine cable and pipeline network is a vital critical infrastructure for EU Member States, and its collapse or damage would significantly affect the vital functions of EU Member States. The VIGIMARE project aims to strengthen the ability of critical infrastructure owners to protect themselves from threats to European submarine critical infrastructure by developing, testing and evaluating an innovative solution that improves security and reduces the risks of physical and cyber attacks on submarine cables and pipelines.

Cyber threats are difficult to define because attack sources and motives are hard to identify, and an attack’s progression is difficult to predict. Unclear boundaries between national, international, public, and private interests further complicate threat identification. In research program we study proactive approach against security threats. This is carried out through the early detection of potential behavior of a system and evaluating the scope of malicious behavior using AI technology.
