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 uses Neodymium isotopes of ocean sediments from the Atlantic Ocean, to trace past ocean circulation throughout the Pleistocene era.

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.
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.
