Research experience

  • 2013
    Post doctorate. Paleoclimate reconstruction from lake sediments based on lake budget modeling and chemical composition of sediments (including radiogenic isotopes); Sedimentology and geochemistry of halite, interglacial climate, development of methods for paleoclimate interpretation from the sediments of the Dead Sea cores obtained by the deep drilling project. U-series dating of sediments including halite

  • 2007 – 2013
    Ph.D studies. Studying lake– and sea–groundwater interaction in the Dead Sea coastal system using radon and radium isotopes, combined with hydrological and geochemical modeling. I focused on seawater circulation in aquifers, its potential effect on coastal water chemistry, radionuclide geochemistry in a coastal aquifer, barite precipitation, adsorption processes and water–rock interaction of the Ca-chloridic brine of the Dead Sea, and showed that saline groundwater circulation in the Dead Sea is a fundamental process affecting the trace element composition of the lake water

  • 2003 – 2006
    M.Sc studies. Studied the effect of sea level changes on coastal aquifers using analytical and numerical modeling and comparing with Dead Sea hydrological and geochemical field data
