RESEARCH INTERESTS
I am interested in past atmospheric-oceanic-terrestrial interactions and the physical mechanisms induced by the different climate forcing components, that lead to the shifts observed in paleo-climate archives.
PAST OCEANS CIRCULATION
During my PhD I used Neodymium isotopes of ocean sediments from the Atlantic Ocean, to trace past ocean circulation throughout the Pleistocene era and especially the "Mid-Pleistocene-Transition".

BIOGEOCHEMISTRY OF CORAL REEFS
-
In my master’s thesis I utilized Uranium-series to trace meteoric diagenesis and date uplifted coral-terraces from the Gulf of Aqaba, Jordan, that were extensively altered to calcite.

In my current research I use nitrogen isotopes to study biogeochemical cycling in modern and past coral reefs.


THE OCEANIC NITROGEN CYCLE
Since joining the AMG lab at MPIC, I have been using Nitrogen isotopes measurements of foraminifera to study the Nitrogen cycle dynamics throughout Earth's history with special emphasis on the Pliocene-Pleistocene Transition when the ice ages cycles began due to the glaciation of the Northern Hemisphere.

DUST EFFECTS ON ECOSYSTEMS
Also, in my PhD, I explored the use of geochemical tools to reconstruct changes in dust supply at the nutrient poor Bahamas Carbonate Platform throughout the Miocene. I tried to trace the time intervals when the Saharan Desert became a significant dust source to this region, and estimate the affects it may have had on the evolution of the platform.
