Marcin Stokowski, Ph.D., is a chemist and biogeochemist currently working as an assistant professor (adjunct) at the Institute of Oceanology, Polish Academy of Sciences (IO PAN). His research focuses on the effects of environmental chemistry changes on fish well-being, with a particular interest in salmonid species and their response to climate change. He uses advanced sensor technologies to study aquatic acidification and basification, ecotoxicology, and the CO2 system in the coastal zone. Additionally, he has a strong interest in sustainable energy innovations and agrochemistry. His work involves interdisciplinary research, international collaborations, and the development of strategies to assess and mitigate the impact of environmental changes on aquatic ecosystems.
