Research focus:
I conduct research into systematics and chorology, molecular phylogenetics and the morphological diversity of trees and shrubs. I am particularly interested in the Robus genus (mainly in respect of chorology and systematics) and Salix genus (patterns of spatial genetic diversity and phylogeography of mountainous species with the use of molecular markers and flow cytometry). I have recently commenced work on studying two related species of hornbeam (Carpinus betulus and C. orientalis) which are a vital component of forests in Europe and West Asia. In my research, I try to assess their susceptibility to climate change, applying several innovative approaches which combine population and landscape genomics with cutting-edge modelling techniques.
