Personal profile
Short presentation
My research takes a holistic approach to understand the ecology and evolution of marine mammals, using ancient, environmental and modern DNA analyses, museum collections and observations in the wild to study the effects of environmental change, pathogens, and human impacts.
I curate the marine mammal collection at the Natural History Museum of Denmark, teach marine mammal biology and research, and supervise multiple PhD, MSc and BSc student projects.
