Graduate Opportunities - Cosmogenic nuclide applications - Purdue University - PRIME Lab

The in situ cosmogenic 14C laboratory at Purdue University's PRIME Lab is seeking motivated new Ph.D. and/or M.S. students interested in working with in situ cosmogenic 14C (in situ 14C) for surficial process and Quaternary geologic studies. In situ 14C is produced by cosmic rays incident on terrestrial materials in a manner similar to other commonly measured in situ cosmogenic nuclides such as 10Be or 26Al. However, its significantly shorter half-life enables one to explore surface processes in ways previously unavailable using only long-lived or stable cosmogenic nuclides.

In particular, we are looking for students interested in advancing in situ 14C analytical techniques and applications, in concert with longer-lived nuclides such as 10Be and 26Al, to study Holocene and late Pleistocene glacial chronologies, surface processes, and neotectonics. Current projects in our lab include a) studies of ice cover histories in East Antarctica as part of a broader, multinational, multi-investigator project to reconstruct and predict the response of the Antarctic Ice Sheet to climate change, and b) innovative cosmogenic nuclide applications for dating offset features along the San Andreas and related fault systems as part of neotectonic studies in southern California. Other potential research areas include projects such as a) developing methods using in situ cosmogenic nuclides to assess long-term soil mixing depths over different timescales and their impacts on landscape evolution in a variety of environments, and b) improving our understanding of global cosmogenic nuclide production systematics - a fundamental consideration in all cosmogenic nuclide applications.

Research experience is desirable, and applicants must have strong quantitative and writing skills. Interested applicants should send a CV and a brief summary of relevant field and/or laboratory experience to Dr. Nat Lifton at [hidden email](http://www.eaps.purdue.edu/people/faculty-pages/lifton.html). Applications received by January 2, 2018 will receive preferred consideration. See http://www.eaps.purdue.edu/for_students/graduate/grad_admissions.html for details on the application process.

Purdue is a major research-extensive university in north-central Indiana that is well known internationally as a center for innovative research involving cosmogenic nuclide methods.  Our research community includes several faculty and a highly productive group of graduate students across earth sciences and physics.  PRIME Lab (the Purdue Rare Isotope Measurement Laboratory) is a dedicated national accelerator mass spectrometry (AMS) facility funded by NSF, NASA and NIH. Purdue University is an Equal Opportunity/Equal Access/Affirmative Action employer fully committed to achieving a diverse student body.

Dr. Lifton will be at the American Geophysical Union Annual Meeting in New Orleans this year if you’d like to chat in person.
