Sarah P. Slotznick





I was Miller Postdoctoral Fellow in the Earth and Planetary Science Department at the University of California, Berkeley.  I received my PhD from the California Institute of Technology in June 2016.


 In January 2020, I will join the faculty of the Department of Earth Science at Dartmouth College.  I'm looking for graduate students--please visit my Dartmouth lab website for more information!


My interdisciplinary research interests center on using iron-bearing minerals to understand the (co)evolution of Earth’s surface environments and life and the fidelity of the sedimentary rock record in preserving ancient bio- and environmental signatures. I integrate field observations with laboratory measurements, incorporating diverse techniques such as optical microscopy, electron microscopy, energy dispersive x-ray spectroscopy (EDS), electron microprobe analysis, synchrotron-based x-ray fluorescence and x-ray absorption near-edge spectroscopy (XANES), secondary ion mass spectrometry, rock magnetism, and paleomagnetism. Using these techniques, I probe questions spanning geologic time from the modern to the Archean, with each time period providing distinct perspectives into the interaction of Earth and the biosphere.
