Tilmann Harder

Prof. Tilmann Harder is a Professor of Marine Chemistry at the University of Bremen and a Senior Scientist at the Alfred Wegener Institute (AWI), leading the Section Ecological Chemistry. His research focuses on marine chemical ecology, natural product chemistry, and biogeochemical processes. He holds roles as Deputy Section Head at AWI, DFG SPP Antarktis Coordinator, and editorial board member for journals like Frontiers in Marine Science. Harder's work integrates advanced analytical techniques (e.g., mass spectrometry, NMR) to study phytoplankton dynamics, dissolved organic matter, and microbial interactions.

Recent projects include pioneering studies on microbiome-photoperiod interactions in diatoms and developing novel methods for siderophore purification. His contributions span Antarctic data integration, marine toxin modeling, and sediment microbial ecology, with over 20 peer-reviewed publications since 2012. Harder collaborates internationally on marine conservation and climate change impacts, emphasizing interdisciplinary approaches to ocean health challenges.
