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.
