CV

I am a researcher at the Faculty of Science, specializing in the intersection of ecotoxicology and global change ecology, with a particular focus on the effects of multiple stress factors on aquatic invertebrate communities. My research involves conducting controlled lab experiments to assess the impacts of stressors such as chemical pollution and warming on the physiology, behavior, and survival of freshwater planktonic organisms like Daphnia sp., benthic insect larvae such as Chironomussp., and insect predators including dragonfly larvae. I also investigate the interactions between these organisms, particularly predator-prey dynamics. Additionally, I examine how these effects may carry over across ecosystems through outdoor mesocosm experiments, and how they influence community structure and ecosystem functions. Through these integrated approaches, I strive to provide a holistic understanding of the environmental effects of anthropogenic disturbances.
