Postdocs

Bob Kopp, STEP Postdoctoral Fellow
The present is a guide to the past, albeit an imperfect one, and the past is one of our best maps to the future: these two precepts guide much research in Earth history and Earth system processes, my own included. I am interested in questions like: How do records of biogeochemical processes get preserved in the rock record? What is the record of life from the early Precambrian to the Recent, and how does it reflect global biogeochemical conditions? What sorts of changes in global biogeochemical and climatic conditions have occurred in the past, and what lessons do these past changes hold for the future? The geological record is filled with evidence of alternate states of the Earth system: from the anoxic Earth of the Archean, to the Snowball Earths of the Paleoproterozoic and Neoproterozoic, to the Hothouse Earth of the Mesozoic and early Paleogene, to the Pleistocene Ice Age Earths. Understanding the nature of alternate Earths like these and the transitions between different states is the best way of testing models of Earth's future.

Nick Swanson-Hysell, Ph.D. Student
The way in which sediments are shaped, moved, and eventually deposited, is governed by the physical and biological processes of a planet's surface. Through the study of ancient sedimentary rocks on Earth we can gain a window into our planet's varied, and sometimes tumultuous, past. My research seeks to peer through this window using a variety of geochemical (stable C, S and Sr isotopes, elemental analyses) and geophysical (paleomagnetic) methods. When such time-series records are paired with detailed field observations they became powerful recorders of Earth history revealing local and global stories about tectonics, climate, the biosphere and their interactions.

Catherine Rose, Ph.D. Student
I am interested in using a multidisciplinary approach to investigate key Earth history events. My research relies on original field observations to generate new datasets and models. Previous projects have focussed on Deep Time glacial deposits and their implications for past climate change. I am eager to begin a detailed sedimentological study of the Neoproterozoic Elatina Formation and equivalents in Australia to enhance our understanding of the physical conditions operating during the extreme climatic perturbations envisaged for a snowball Earth. In addition, I aim to broaden my research skills using isotope geochemistry, magnetostratigraphy and geochronology to constrain the timing, rates and durations of hallmark events in this Era. My interests are not solely restricted to processes on Earth and I am enthusiastic to explore past and recent Martian surface processes and their role in the overall evolution of the planet's geologic history and internal evolution.



Undergraduate Students
The Princeton Earth History Group also employs undergraduate students in research and teaching projects. Currently, Julie Dickerson ('10) is making line drawings to accompany a forthcoming manuscript about Lonar Crater in India, Becca Levin ('10) is preparing Australian samples for geochemical analysis, Tim Keeler ('11) is writing matlab routines to graphically display and statistically evaluate lithostratigraphic and chemostratigraphic data, Lija Treibergs ('11) is preparing Moroccan samples for geochemical and petrographic analyses, and Nora Xu ('11) is training for field work with Catherine Rose in Australia during the Summer of 2008. Julie Michelman (Carleton College '11) also will be joining our team this summer.
