Daniel Herlemann

Daniel Herlemann is a researcher affiliated with the Leibniz Institute for Baltic Sea Research Warnemünde since 2023 and the Estonian University of Life Sciences since 2018. His work focuses on environmental microbiology, particularly the dynamics of bacterial communities in marine and brackish water systems.

Herlemann investigates the salinity gradient of the Baltic Sea, analyzing transitions between marine and limnic bacterial species across over 200 locations. His research includes microbiome-host interactions, Vibrio vulnificus proliferation, and impacts of industrial salt discharge and climate change on microbial communities.

Key trends from his recent publications (2023–2025) highlight interdisciplinary studies on marine pathogen ecology, microbial community resilience, and environmental drivers like salinity and temperature. He has co-authored 12 papers in this period across journals such as Molecular Ecology, Frontiers in Microbiomes, and Communications Earth & Environment, often collaborating with teams in Germany and Estonia.

Herlemann's work also extends to clinical microbiome research, notably studying intestinal bacterial shifts in liver cirrhosis patients and vitamin D effects on Crohn’s disease microbiomes. His methodological expertise includes molecular biological techniques and 18S rDNA amplification for protist diversity.
