His research interests encompass algal taxonomy, biodiversity, ecology, biogeography, and conservation biology, with a particular focus on the diversity of freshwater algae in high-altitude lakes of the Eastern Black Sea Region and the Kaçkar Mountains of Türkiye. He has made substantial contributions to the freshwater algal flora of Türkiye through the discovery and documentation of numerous new genera and species records, particularly among the Desmidiales. His current research also explores the biodiversity of high-mountain freshwater ecosystems and their ecological responses to environmental and climate change.
