Research Interests

I am an aquatic ecologist with a strong background in fish behavior and physiology. My research focuses on how ecological pressures, including climate change and biological invasions, shape the functional phenotypic diversity of aquatic animals. I aim to elucidate the dynamic interactions between the traits of individuals and the functioning of the whole ecosystem. By understanding these processes, my work contributes to the effective conservation and management of aquatic biodiversity.


Ich bin ein aquatischer Ökologe mit einem starken Hintergrund in Fischverhalten und -physiologie. Meine Forschung konzentriert sich darauf, wie ökologische Belastungen, einschließlich des Klimawandels und biologischer Invasionen, die funktionelle phänotypische Vielfalt aquatischer Tiere beeinflussen. Ich strebe danach, die dynamischen Wechselwirkungen zwischen den Merkmalen einzelner Organismen und dem Funktionieren des gesamten Ökosystems zu ergründen. Durch das Verständnis dieser Prozesse trägt meine Arbeit zur effektiven Erhaltung und Verwaltung der aquatischen Biodiversität bei.
