AT THE MAX PLANCK INSTITUTE FOR CHEMISTRY
I have recently joined the AMG group where I use nitrogen isotopes to study biogeochemical cycling in modern and past coral reefs and in the oceans.
2014 - 2020
Thesis title: Geochemical studies of marine sediments from the Atlantic Ocean: Implications for past transitions in ocean circulation and dust deposition.
Under the supervision of profs. Jerry McManus, Steven L. Goldstein and Gisela Winckler
During my PhD I used Neodymium isotopes of ocean sediments from the Atlantic Ocean, to trace past ocean circulation throughout the Pleistocene, including the highly debated Mid Pleistocene-Transition interval, when the Earth’s glacial interglacial cyclicity shifted from 41 kyr to 100 kyr. In addition, I have accomplished original research using Th concentrations, Lead and Neodymium isotopes and trace elements patterns, 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.
AT THE INSTITUTE OF EARTH SCIENCES, THE HEBREW UNIVERSITY OF JERUSALEM
Thesis title: Calcitic corals from the northern red sea as paleohydrological monitors.
Under the supervision of profs: Moredechai Stein, Boaz Lazar and Amotz Agnon.
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.
