Kirsi Helkala
Currently, I am a professor at the Norwegian Defence Cyber Academy, Cyberingeniørskolen (called earlier Forsvarets Ingeniørshøgskole). Norwegian Defence Cyber Academy is part of the Norwegian Defence University College. I have also worked as a research professor at the Peace Research Institute Oslo (PRIO) during September 2020 - December 2023. Earlier I have worked at Gjøvik University College, that is now part of NTNU. I hold a Master of Science degree in mathematics from the University of Joensuu, Finland and a PhD within information security from the University of Oslo, Norway (PhD dissertation: Authentication in Health Services). I teach mathematics and supervise information and cyber security related student workshops, term papers and thesis. My research interest lays on human factor in cyber security.
