My main topic of research and observation are poplars. Since 2017 I've been collecting these plants for Arboretum in Rogów. We try to observe various factors that will allow us to accurately classify poplars in such a complex systematics.
Since 2017 I have been simultaneously involved in Landscape Architecture, which I study at the Warsaw University of Life Sciences, and since 2018 I'm a member of the Polish Dendrological Society.
I invite you to cooperation.
