My research interests: leaf functional traits of plants from different climate and with different ecological strategies; leaf architecture and photosynthetic elements arrangement; relationships between leaf gas-exchange and mesophyll structure; development the methods of plant quantitative anatomy; 3D-modelling the leaf spatial structure; creation the database on leaf functional traits. I participated in research field expeditions to Middle Urals taiga, Jamal tundra, South Ural steppes, Kazachstan steppes and deserts, South Siberia taiga and steppe, Trans-Baikal region, Buryatia, Mongolia, Gobi desert.
