In my work as nuclear science freelancer, I build on what I did before for many years: developing technology road maps, plan budgets and projects, supervising staff and contractors enhancing, testing and implementing cutting edge scientific methods and computer algorithms for operational data processing. I am employed by ISTI as senior expert specialized on effective strategies for applying nuclear forensic analysis methodologies on atmospheric radioactivity data to facilitate nuclear explosion monitoring under the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Also, I promote the use of data from the CTBT International Monitoring System (IMS) for civil and scientific application. Training and education of students and young professionals is crucial for developing capacities and empowering the future generations.
