We seek to hire two Postdoctoral Fellows in the field of microbial ecology and biogeochemistry. For both, research will use theory and mathematical modeling as tools to understand how microbial ecological interactions drive global-scale marine nutrient cycling. One position will focus on aspects of the marine nitrogen cycle, with research aiming to understand how nitrogen-cycling microorganisms may provide feedbacks to current changes in the climate system. Specific project focuses are flexible, and may include, for example, the ecology and biogeochemical impacts of aerobic and anaerobic metabolisms in anoxic marine zones or the global-scale ecology of nitrification in relation to the carbon cycle. A second position will focus on the diverse communities of microorganisms that consume nonliving organic matter, with research aiming to understand how microheterotrophic ecological interactions give rise to observed community composition patterns and carbon cycling at large scales. Specific project focuses may include the factors maintaining the diversity of free-living microheterotrophic functional types or the controls on the spectrum of organic carbon turnover rates. Fellows will collaboratively design and conduct cutting-edge research, publish results in peer-reviewed journals, and present results at scientific conferences.

Applicants should have a Ph.D. or equivalent by the start of the appointment in the natural sciences and/or mathematics. We seek candidates with experience in scientific programming and numerical modeling. Though a background in oceanography, biogeochemistry, ecology, or microbiology is helpful, all applicants with excellent critical thinking and quantitative analysis skills, excellent oral and written communication skills, and demonstrated ability to drive projects forward in a timely manner will be considered. Additionally, we seek candidates who will work to increase the representation of historically underrepresented groups in the geosciences.

Fellows will join the Department of Global Ecology (DGE) https://dge.carnegiescience.edu/ at the Stanford University campus of the Carnegie Institution for Science. Fellows will work primarily under the guidance of Dr. Emily Zakem https://ezakem.scripts.mit.edu/emilyzakem/, with opportunities to collaborate with other researchers at DGE, Stanford University, and beyond. Founded in 2002, scientists at DGE conduct basic and applied research into the interactions among the Earth?s ecosystems and people. The Carnegie Institution has a commitment to scientific excellence and diversity; we strongly encourage applications from candidates who will enrich and foster a culturally diverse and inclusive environment.

The start dates for the positions are flexible, and review of applicants will be ongoing until the positions are filled. Initial appointments are for one year, with possible renewal. Carnegie offers competitive salary and comprehensive benefits. In addition, a budget is available to partially reimburse relocation expenses for successful candidates and their immediate families. Applications consist of a CV, a one-page statement of research interests, and contact information for three references submitted through DGE’s application portal https://jobs.carnegiescience.edu/jobs/ (position #1 https://jobs.carnegiescience.edu/jobs/postdoctoral-opportunity-microbial-ecological-modeling-of-the-marine-nitrogen-cycle/ and position #2 https://jobs.carnegiescience.edu/jobs/postdoctoral-opportunity-ecological-modeling-of-marine-microheterotrophic-communities/). Please contact Emily Zakem (ezakem@carnegiescience. ezakem@carnegiescience.eduedu ezakem@carnegiescience.edu) with any questions about the positions.
