Research Topics
Ocean Biogeochemistry and Climate through Earth's History
Anthropocene
We investigate the impact of anthropogenic activities on the marine N cycle
Quaternary
We focus on the role of the ocean in driving atmospheric CO2 during ice ages
Pliocene
The Pliocene is a geological analogue to study the Earth's system in a warmer climate
Cenozoic
We also study long-term climate changes over the Cenozoic era, i.e. the past 65 My
Terrestrial Climate and Environmental Changes in the past
Speleothems
We analyze biomarkers and N isotopes to reconstruct terrestrial climate in the past
Lakes
We analyze biomarkers and their isotopes to reconstruct terrestrial climate in the past
Loess
We analyze biomarkers and their isotopes to reconstruct terrestrial climate in the past
Ice cores
We use N isotopes to study atmospheric circulation and chemistry in the past
Biogeochemical changes in the modern Ocean
N cycle
We use N and O isotopes of nitrate to study N cycle dynamics in the modern ocean
Proxy validation
Ground truthing studies of different environmental proxies in the modern ocean
Trophic ecology of extant and extinct taxa
Lab experiments
We study the N isotopic composition of enamel in controlled experiments
Proxy Validation
We analyze enamel N isotopes in modern ecosystems to asses its application in the past
Trophic ecology
We use N isotopes in enamel to study the trophic evolution of extant and extinct taxa
Hominin diets
We use N isotopes in enamel to study the dietary evolution of early hominins
Cancer diagnosis and metabolism
Mice Models
We study the potential of N isotopes for cancer diagnosis and metabolism in mice
Human Models
We analyze N isotopes in human biopsies to study cancer diagnosis and metabolism
