The Lamont-Doherty Earth Observatory (LDEO) of Columbia University located in Palisades, New York, invites applications for up to two Postdoctoral Research Scientists to conduct research in the fields of climate & glacial geology and cosmogenic nuclide science. The successful candidate(s) would join the LDEO Cosmogenic Nuclide Laboratory (https://cosmo.ldeo.columbia.edu/) and apply novel cosmogenic isotope techniques (10Be and in situ 14C from new extraction line) within transdisciplinary multi-institution projects aimed at 1) evaluating the global response of mountain glaciers to past, modern and future climate, the contribution to sea-level rise and impacts on frontline communities down- stream, and 2)
