Applications are invited to fill a full-time, 3-year position in the Oceanography Department at the University of Hawaii at Manoa (K. C. Ruttenberg, Honolulu, HI), in collaboration with the Dept. of Earth and Environmental Science at Columbia University and Lamont-Doherty Earth Observatory (LDEO), (S. T. Dyhrman, Palisades, NY), to study the molecular biogeochemistry of dissolved organic phosphorus (DOP). We are looking for postdoctoral candidates with a strong background in microbial and/or nutrient biogeochemistry, with interest in addressing processes at the interface of biogeochemistry and microbial oceanography. The primary institutional home of the successful candidate will be in the nutrient biogeochemistry lab of Ruttenberg, in the Oceanography Department at the University of Hawaii at Manoa (UHM), with opportunities for cross-training in microbial oceanography with Dyhrman at Columbia University-LDEO. The project supporting this postdoctoral position is a collaboration between Ruttenberg and Dyhrman, and integrates transcriptome profiling, LCMS, and enzyme assays with the primary research goal of characterizing DOP molecular weight distribution, composition and bioavailability as a function of phytoplankton physiology and the N:P ratio of the (natural or culture) growth medium. This research will use a combination of field sample analysis, laboratory biogeochemistry, and culture work at both UHM and LDEO. Applications will be considered starting July 1, 2018, and continue until a suitable applicant is chosen.
