Postdoctoral Position in Geochemistry

Clumped Isotope Geochemistry of Organics in Carbonaceous Meteorites

Applications are invited for a postdoctoral position in clumped isotope geochemistry within Caltech's Division of Geological & Planetary Sciences. The successful applicant will work with Professor John Eiler and Dr. Amy Hofmann (JPL) on the collection and interpretation of clumped isotope signatures in polycyclic aromatic hydrocarbons (PAHs) from different classes of carbonaceous meteorites.

Responsibilities include subsampling powders from the identified meteorites, wet chemical extraction, separation, and quantification of PAHs from the sampled powders, and isotopic analysis of the extracted PAHs using GC-Orbitrap-based mass spectrometry.

The selected candidate is expected to begin as soon as possible. The initial duration of the position is one year.

Applicants for this position must have a PhD in geochemistry, organic geochemistry, isotope geochemistry, organic chemistry, or equivalent by the time of the appointment. Additional required qualifications include significant organic chemistry ‘wet lab' experience and a working knowledge of the principles of stable isotope geochemistry. Experience with geochemical analytical techniques, including GC-MS and isotope ratio mass spectrometry, familiarity with organic stable isotope geochemistry and/or meteoritics literature, and experience manipulating small, rare, valuable geological samples is strongly preferred but not required.

Applicants must provide a CV including a complete list of publications; a 1-2 page statement describing their research interests and experience; and the names of three individuals who can provide letters of recommendation. Application materials should be sent to Amy Hofmann (amy.e.hofmann@jpl.nasa.gov) no later than August 1, 2022. Questions regarding the position should be directed to Dr. Amy Hofmann (amy.e.hofmann@jpl.nasa.gov) and Professor John Eiler (eiler@caltech.edu).

We are an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, or national origin, disability status, protected veteran status, or any other characteristic protected by law.
