Profile
Biography
My research spans a wide range of topics, including fish physiology, fish ecology, water quality, biogeography, environmental management, and conservation. I am particularly interested in understanding how organisms interact with their habitats and adapt to extreme environmental conditions. My work focuses on hypoxia, whether it occurs naturally in tropical tidal ecosystems like mangroves or results from human activities such as nutrient enrichment in regions like the Baltic Sea. To address these questions, I employ diverse methodologies, combining field-based observations and data collection with laboratory techniques such as respirometry, haematology, morphological analysis, and the use of natural tags like otoliths. By integrating these methods, I aim to explore broad ecophysiological processes and provide insights that contribute to the conservation and sustainable management of coastal ecosystems.
