Erez Jonathan, HUJI, Faculty of Science, The Institute of Earth Sciences


Foraminifera, corals, stable isotopes, coral isotopes, biomineralization



  • The laboratory focuses on
  • Biomineralization mechanisms, internal carbon and calcium cycling in marine symbiotic associations (foraminifera and corals)
  • Experimental studies on stable isotopes and trace elements in live foraminifera and corals in order to develop new paleoceanographic proxies
  • Carbon isotopic fractionation and carbon limitation in algae during photosynthesis
  • Nutrient fluxes between coral reefs and the open ocean

Research provided

  • Measurements of biomineralization rates of marine organisms under controlled conditions
  • Video microscopy and confocal microscopy or the cellular and tissue processes involved in biomineralization of corals and foraminifera


  • A highly skilled, renown researcher utilizing state-of-the-art equipment and technologies

Available equipment

  • Video fluorescence microscopy and spectral microscopy system
  • Confocal microscopy
  • Microelectrodes for Oxygen pH and Ca2+
  • Mass spectrometry for C and O isotopes


  • Jonathan Erez, PhD
