Meet the researcher: Catherine Legrand

Professor Legrand’s internationally recognized research focuses on aquatic microbes and the health of aquatic ecosystems under human pressure. Her work combines marine ecology with cutting-edge omics technologies to uncover the structure and function of microbial communities, particularly in brackish environments like the Baltic Sea. She has contributed to the discovery of globally distributed brackish microbiomes and advanced understanding of seasonal dynamics in planktonic food webs and nutrient cycling.
