Overview

Urban Tillmann is affiliated with the Alfred Wegener Institute for Polar and Marine Research in Germany. Their research primarily focuses on environmental science, earth and planetary sciences, and biochemistry, genetics, and molecular biology. This work intersects heavily with subfields such as environmental chemistry, oceanography, molecular biology, ecology, and organic chemistry.

The main topics that characterize Urban Tillmann's scientific contributions include marine toxins and detection methods, marine and coastal ecosystems, protist diversity and phylogeny, microbial community ecology and physiology, marine biology and ecology research, chemical synthesis and alkaloids, and aquatic ecosystems and phytoplankton dynamics.

Recent publications associated with Urban Tillmann illustrate the scope of their research interests. These include:

  • "The Mixoplankton Database (MDB): Diversity of photo-phago-trophic plankton in form, function, and distribution across the global ocean" (2023, Journal of Eukaryotic Microbiology)
  • "Unknown Extracellular and Bioactive Metabolites of the Genus Alexandrium: A Review of Overlooked Toxins" (2021, Toxins)
  • "Morphological and phylogenetic data do not support the split of Alexandrium into four genera" (2020, Harmful Algae)
  • "Recommendations for epitypification of dinophytes exemplified by Lingulodinium polyedra and molecular phylogenetics of the Gonyaulacales based on curated rRNA sequence data" (2021, Harmful Algae)
  • "A Mediterranean Alexandrium taylorii (Dinophyceae) Strain Produces Goniodomin A and Lytic Compounds but Not Paralytic Shellfish Toxins" (2020, Toxins)

Urban Tillmann frequently publishes in specialized venues, contributing extensively to journals such as:

  • Harmful Algae
  • Toxins
  • Zenodo (CERN European Organization for Nuclear Research)
  • Scientific Reports
  • Microorganisms

The research collaborations of Urban Tillmann include multiple coauthors with whom they have frequently worked. Notable collaborators are Bernd Krock, Stephan Wietkamp, Marc Gottschling, Mona Hoppenrath, and Jan Tebben.
