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.
This RII Track-I project, named ‘Ike Wai (from the Hawaiian ‘ike, meaning knowledge, and wai, meaning water) tests the central hypothesis that hydrogeology of the Hawaiian islands depends critically on the internal structure of the volcano. ‘Ike Wai will collect new geophysical and groundwater chemistry and microbial data, integrate these data into new, detailed groundwater models, and generate a much improved understanding of subsurface water location, volume and flow paths. Data and outputs from ‘Ike Wai will provide decision making tools to address challenges to water sustainability from climate variability, increasing population demands, and water contamination. The successful applicants for these three-year postdoctoral positions will interact with scientists and students across disciplines and actively engage in professional development training in areas such as leadership, diversity, pedagogy and mentoring. Within the objectives and scope of ‘Ike Wai, applicants will have significant flexibility in defining projects that capitalize on the diverse expertise and collaborative interests of the team as they relate to water sustainability. ‘Ike Wai postdoctoral researchers will participate in a work environment that encourages knowledge of, respect for, and development of skills to engage with diverse communities in Hawai‘i and the Pacific on issues surrounding water sustainability. Applications due January 24, 2017.
