I have been long involved in nuclear measurements and analyses within the Radiation and Nuclear Safety Authority (STUK), Finland. Initially I worked as a scientist devoted to health impact of ionizing radiation. Later I served as the Head of Laboratory for Airborne Radioactivity and for Security Technology. Under my leadership several innovative technologies were discovered and implemented for the Finnish national safety and security. One of my most prominent achievements is the development of reachback technology which truly puts the nuclear analysts virtually to middle of field operations although all data processing happens far away in an analysis centre.

By education I am a doctor of physics, PhD, in nuclear engineering. I have served five years as the evaluation officer in the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Vienna. I have been the key person to pursue novel approaches and technologies for the European Safeguards Research and Development Association (ESARDA). I have been involved in writing several international documents on nuclear security for the International Atomic Energy Agency (IAEA) and the Global Initiative to Combat Nuclear Terrorism (GICNT). I have worked as a coordinator for EC/JRC/ERNICIP on Radiological and Nuclear Threats to Critical Infrastructure.
