Essential Job Duties
The Baars group (https://baarslab.wordpress.ncsu.edu) at NC State University invites applications for a Postdoctoral position. We use new analytical approaches in a biological context to profile and characterize biologically secreted metabolites that are triggered by abiotic and biotic interactions in the environment.
This position will focus on molecular controls on metal limitation and toxicity via secreted metal chelating metabolites (the ‘chelome’) in soil and freshwater. There are almost no measurements of biogenic chelators in the field because of the technical challenge to analyze these compounds at trace-concentrations in the extremely complex soil matrix. There is an urgent need for direct measurements of the concentrations, structures, and chemistries of secreted biogenic chelators in soil and freshwater to understand the extent of limitation of plant productivity and microbial activity by iron and other required or toxic metals.
The first goal of this position will be the implementation of a new analytical platform to analyze soil and freshwater samples for biogenic metal chelators and provide answers to these questions under environmentally relevant conditions. The instrumental approach utilizes recently published methods based on the sensitivity and separation power of high-resolution LC-MS and LC-
. Ancillary analyses, for example by electrochemistry, can also be performed. Further projects can involve controlled cultures with microorganisms and plants, isolation and chemical characterization of new secondary metabolites, the development of methods for imaging mass spectrometry, and system-wide exometabolomics.
Apart from the direct interest for agriculture and human health (nutrition, toxic metal uptake, and sequestration), the results will provide insight into metal controls on terrestrial carbon and nitrogen fixation.
The postdoc will publish and present results in international peer-reviewed journals and at scientific meetings and actively seek and submit proposals to funding agencies as opportunities become available for postdoctoral fellowships. The responsibilities also involve guidance to undergraduate and graduate students in the laboratory.
Ph.D. or equivalent doctorate (e.g., M.D., D.V.M., Sc.D.) in appropriate field awarded no more than five (5) years from initial date of postdoctoral appointment.
Departmental Required Skills
Ph.D. in Environmental Chemistry, Chemical Biology, Microbiology, Biogeochemistry, or a related field.
Preferred Experience, Skills, Training/Education
The ideal candidate will combine strong skills in instrumental analysis with prior experience in any of the following fields: microbiology, microbiome research, metals in biology, biogeochemistry, metabolomics, natural products research or related areas.
Required License or Certification
The position will be available as early as July 2018 for up to three years based on annual performance evaluation. Formal applications will include a Cover Letter, CV, and contact information for three references.

This is the new ncsu.edu, launched in August 2014. This redesigned site offers users an experience that reflects NC State itself. Innovative. Purposeful. Modern. Regular users will notice something immediately about this site: There’s less of it. In redesigning and rebuilding ncsu.edu, we considered the value of every page and subpage, removing content that lacked utility and erasing barriers between users and the information they seek. We took a similar approach to design. The redesigned site is cleaner and brighter, giving its content room to breathe and tell our story. We also streamlined and clarified the organization of ncsu.edu. Primary navigation on our homepage and throughout ncsu.edu is organized around topics: About NC State, Admissions, Research, Academics, Partnerships, Campus Life, Outreach and Athletics. On these pages and the homepage itself, you’ll learn about our world-leading faculty and staff, high-performing students and the solution-driven research and scholarship they produce.
