I am an ichthyologist and work at the Institute of Technology and Life Sciences - National Research Institute (Poland). My research activity is mainly focused on the aquatic environment, examining changes in the biodiversity of fish, amphibian and other organisms' habitats. For several years I have been researching small, mid-field water bodies, taking into account climate change and human activity. Recently, I have been interested in small rivers and changes in biodiversity as a result of dredging.
