I have been working in the Finnish Environment Institute since 2019 as an experts and a researcher. My duties have been diverse, and I have worked with threatened habitats and species (e.g. regional prioritization negotiations of threatened species protection). Recently I have ventured into international development projects targeting environmental management (Türkiye and Armenia). Before joining the Finnish Environment Institute I was a researcher in the University of Turku, studying primarily dragonflies.
