Lamont-Doherty Earth Observatory of Columbia University invites applications for Postdoctoral Fellowships in the fields of Earth and environmental sciences. Candidates should have recently completed their Ph.D. or should expect to complete their degree requirements by September 2017. Researchers at the Observatory work to understand the dynamics of the Earth’s chemical, physical and biological systems, from the core to the upper atmosphere, including Earth’s interactions with human society. Our scientists lead research in the fields of solid Earth dynamics; ocean, atmospheric and climate systems; cryospheric dynamics; paleoclimate and biogeoscience. The principal selection criteria for Fellows are scientific excellence and a clearly expressed plan to investigate problems at the forefront of Earth science. Applications from all related fields are welcomed. Fellowships are supported institutionally for 24 months, include a $7,500 research allowance, and carry an annual salary of $64,000. Successful candidates will be encouraged to apply for external funding and may be eligible for further internal awards and positions. LDEO is especially interested in qualified candidates whose record of achievement will contribute to the diversity of the Observatory’s scientific personnel. The deadline for applications is November 14, 2016.
