Education

Ph.D. Lamont-Doherty Earth Observatory of Columbia University (2004).

Research Interests

  • Mechanisms and physical conditions of planetary differentiation including:
    • core formation on Earth and on other planetary bodies
    • creation, stability and evolution of the lithosphere
  • Geochemical evolution of the Earth through time
    • current oxidation state of the mantle
    • subduction zone volcanism and volatile cycling
  • Chemistry at the core-mantle boundary and its influence on geochemistry at Earth’s surface

  • Development and application of new experimental techniques to explore problems in solid earth geochemistry and dynamics (piston cylinder, multi-anvil, diamond anvil cell, XANES spectroscopy)
XANES analysis At left:Rebecca Fischer positions a sample for XANES analysis at beamline X26A, part of the National Synchrotron Light Source at Brookhaven National Laboratory. Rebecca participated in Smithsonian’s Research Program for undergraduates in the summer of 2007.
Below: EC positions a diamond anvil cell for in situ x-ray diffraction and double-sided laser heating at GSECARS beamline at the Advanced Photon Source, Argonne National Laboratory. Experimental set-up is depicted at right. Lower left, EC laser heats the sample remotely from outside the experimental "hutch" which has a thick lead lining to protect users from synchrotron radiation.
