Dr Sebastian Breitenbach

Associate Professor

School: Geography and Natural Sciences

I am head of the EnMaR (Environmental monitoring and reconstruction) research group.

I am a palaeoclimatologist with strong affinity to caves and carbonates. I use carbonate chemistry and stable isotope geochemistry as tools to reconstruct past environmental and climate conditions. Ideally I then use these reconstructions to inform archaeologists, anthropologists and other interested parties and the public about the influence that climate has on society. To this end I follow a holistic, multi-disciplinary approach and work closely with experts from a broad range of research fields.

My research is globally spread as I select sites that are best suited for the research question at hand. Among other places, I work in Germany, Siberia, India, New Zealand, and Belize.

I am currently establishing clumped isotope thermometry in our new stable isotope laboratory.

Research Themes and Scholarly Interests

I am a palaeoclimatologist with strong affinity to caves and carbonates. My research interest includes palaeoclimatology, geothermometry, geochronology, climate-human interaction, geochemistry, continental environmental change, and human adaptation/behaviour in response to climate change.
