Research focus:
For years, my research has focused on the micromorphology of plant surfaces, with particular emphasis on leaf trichomes and epicuticular waxes on leaves and stems. The primary tool in these studies is the scanning electron microscope (SEM). The data are used to address systematic issues and describe new plant taxa.
An important aspect of my research is the analysis of ecological niches and the distribution ranges of tree and shrub species, such as representatives of the genera Viscum and Rubus. I am also interested in shape analysis using modern morphometric methods and the study of biases in biodiversity and biogeographic data.
I am also engaged in the study of biological collections, particularly their digitisation and the creation and management of databases. As a strong advocate for herbarium data mobilisation, I aim to increase the accessibility of these data and expand their use in research.

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

Research focus:
The scope of my research includes population and conservation genomics, comparative phylogeography, and molecular taxonomy of woody species. Currently, I am focusing on adaptive genomics and the role of hybridisation as a mechanism enhancing the adaptive potential of forest trees in the face of climate change. To investigate this, I selected two closely related species, Fagus orientalis and F. sylvatica, which hybridize in a narrow contact zone in southeastern Europe.
In my research, I integrate genomics and ecological approaches with advanced spatial modelling techniques to explore how forest trees respond to global climate change.
Keywords:
evolutionary biology, hybridisation, landscape genomics, local adaptation, phylogeography

Research focus:
The main areas of my research include biogeography, population genetics, phylogenesis, ethnobotany, and demography of woody species, with particular attention to endemic and relic taxons.
My current focus is on studying flora that can be found in biodiversity hotspots (the Mediterranean Sea basin, Caucasus, the Irano-Anatolian region) and within European mountain ranges (the Alps, the Carpathian Mountains, and the Pyrenees).
I analyse spatial data concerning the incidence of specific species and their reaction to environmental factors, which allows me to determine the spatial patterns for plant incidence. The collected information on genetic resources, potential distribution and interactions with the environment facilitate the planning of strategies for the protection of individual species and entire ecosystems.
My research activities also include cooperation with experts specialising in such scientific disciplines as biological sciences, forestry,
and medical sciences.
