Open postdoc position

The Isotopologue Paleosciences Laboratory (IPL) in the Department of Earth and Environmental Sciences at the University of Michigan is interested in hiring a postdoctoral research fellow who will help further our studies of triple oxygen isotope variations in Earth system processes. Examples of systems that might be pursued include modern waters, caves / speleothems, plants (e.g., tree-ring cellulose), animals (e.g., bioapatites), and their respective relationships with (paleo)climate and (paleo)environment. There is also opportunity for application to shallow crustal systems (e.g., diagenesis, distal contact metamorphism, hydrothermal mineral deposits). Some of these systems will include method development in the high-precision triple oxygen isotope analysis of organics and phosphates. Candidates are expected to have a Ph.D. in geology, geochemistry, climate, ecology, or related fields. A strong analytical background in isotope geochemistry is required.

IPL is directed by Dr. Naomi Levin and Dr. Ben Passey.  The physical lab is centered around two Nu Perspective-IS mass spectrometers and associated equipment capable of high-precision triple oxygen isotope analysis of waters, carbon dioxide, and carbonates. Capabilities also include clumped-isotope analysis of carbon dioxide and carbonates, IR laser-ablation GC-IRMS of bioapatites (and potentially IR laser-fluorination of silicates and oxides), and traditional CNOH isotope measurements of carbonates and organics (NuCarb, EA, TC-EA). We currently have a vibrant group of three graduate students, one postdoc, and several undergraduate students. We are looking forward to having another talented person join our team!  The department has an active core of climate / geochemistry-oriented research groups and a culture of collaboration with porous lab boundaries.

Please send your full CV, a 1-2 page statement of research goals and interests, and the contact information for three references to Your statement should include specific ideas about what you might want to accomplish as a postdoc in IPL. You should also indicate your desired start date. We will begin to review applications on September 10, with the aim of filling the position as soon as possible but later start dates will be considered for the right candidate.

The appointment will initially be for a single year and is renewable for a second year upon satisfactory performance. The position comes with competitive salary and benefits. Ann Arbor is a terrific place to live and work. The University of Michigan is an equal opportunity affirmative action employer.
