Associate Professor

The marine mammal ecology and evolution group seeks to document and understand effects of environmental change, pathogens, and human activities on the abundance, distribution, diversity and speciation of marine organisms with a focus on marine mammals, their prey and predators.

Our research is interdisciplinary with a focus on ancient, environmental and modern DNA analyses, museum collections and observations in the wild.

We teach Marine Mammal Biology and Research, Molecular Ecology, Arctic Biology, and Danish Vertebrate Zoology, and are always looking for new Postdocs, PhDs, MScs and BScs student to join our group.
