Dr David Bajnai

Hello, my name is Dr David Bajnai (pronounciation: ˈdaːvid ˈbɒjnɒi). I am a senior researcher in geochemistry at the University of Göttingen.

Research Interests

My research focuses on reconstructing past environmental conditions, particularly surface temperature evolution, across Earth’s history. I use dual clumped isotope (Δ₄₇ and Δ₄₈) and triple oxygen isotope (Δ’¹⁷O) proxies in carbonates to generate quantitative temperature reconstructions, including from archives where conventional proxies can yield biased estimates. By disentangling primary environmental signals from biological and diagenetic overprints, I improve the reliability of paleoclimate records and help fill gaps in Earth’s climate history. In parallel, I investigate biomineralization processes in marine organisms to understand the mechanisms of shell formation and how environmental information is encoded in biominerals.
