Postdoctoral fellowship (2 years) in the area of

The Trace Element Speciation Analysis Research group develops and implement novel and advanced analytical methods and experimental strategies to study chemical and biological processes of trace metal compounds in ecosystems and biological systems.A major part of the research program is focused on advancing the molecular level understanding of formation of methyl mercury in aquatic ecosystems.We now seek a postdoctoral researcher to conduct fundamental studies on mercury-sulfide chemistry in controlled model systems.The project includes design and measurement on model systems in a controlled laboratory environment, and chemical modelling of the results.The aim is to increase the knowledge about mercury-sulfide speciation, and thereby decrease uncertainties regarding the concentrations of bioavailable Hg species under different chemical conditions.Applicants should posses a doctoral (Ph.D) degree, preferably not more than three years old, within Hg biogeochemistry or closely related fields.Experimental work in the laboratory will include using analytical techniques for the determination of mercury species in aqueous and solid phases, based on GC-ICPMS and synchrotron based X-ray Absorption Spectroscopy (XAS), respectively.Chemical speciation modelling will be used to further assess the speciation of dissolved mercury.Mercury isotope tracer experiments to quantify rates of methylation and demethylation may also be applied.It is therefore considered a merit with experience from Hg speciation analysis with isotope tracers, IDA, synchrotron based XAS techniques, and chemical speciation modelling.For complete information see: http://www.umu.se/english/about-umu/news-events/grants/223-325-10 The position will be based on a stipend for a duration of two (2) years.Your application should contain a cover letter summarizing your research interests and motives to why you are interested in this particular position.It should also include: (1) a curriculum vitae, (2) a publication list, (3) transcripts of degree certificates, and (4) names and contacts of 1-3 references.The application should not include separate articles or theses.For further information, please contact: Assoc.Prof.The procedure for recruitment to the position is in accordance with the Higher Education Ordinance (chapt.12, 2 ) and the decision regarding the position cannot be appealed.Documents sent electronically should be in MS Word or PDF format.
