Postdoctoral Associate, Sediment sulfur cycling (closes 4/1/2019)

Postdoctoral opportunity in sediment sulfur biogeochemistry, Large Lakes Observatory, University of Minnesota Duluth

We seek a postdoctoral researcher to investigate the biogeochemical pathways of organic sulfur in low-sulfate aquatic sediments, in the framework of a NSF-funded project ( A successful candidate will join an interdisciplinary team of geochemists, geomicrobiologists, and modelers to investigate how, under conditions of scarce inorganic sulfur, mineralization of organic sulfur contributes to diagenetic reactions, generates reactive sulfur intermediates, and supports microbial communities. We seek an experimental scientist with strong proficiency in analytical techniques and interest in applying geochemical knowledge to solving fundamental problems. Experimental work will include offshore fieldwork on the Great Lakes and laboratory studies. Applicants should have a demonstrated record of conducting research in a relevant field, and an excellent record of scholarly publications. They would be expected to conduct independent research, assist with lab and field coordination activities, and participate in supervision of graduate students. Preference will be given to candidates who have excellent written communication skills, experience in limnological or oceanographic work, experience in sediment geochemistry, especially in the cycling of sulfur, or experience in numerical modeling.

The position is to begin between June and October 2019, for a term of 18 months. Salary up to $49,000/year will be commensurate with qualifications.

The Large Lakes Observatory, located on the Duluth campus of the University of Minnesota, is an interdisciplinary research department dedicated to oceanographic studies of large lakes worldwide and offers excellent professional development opportunities.
