Postdoctoral Research ociate - (Raleigh, NC)

Position Number: 00106912 Essential Job ignments: 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.
