Job Description

Mission

The Environmental Microbiology Laboratory (EML) studies microbial and abiotic processes in the subsurface with a focus on contaminant transformations. The research performed at EML aims at understanding the mechanistic underpinnings of these processes and at providing science-based solutions to environmental challenges including aquifer contamination, nuclear waste disposal, and greenhouse gas emissions. In addition, constraining the role of reduction mechanism on uranium isotope fractionation is a long-term goal of the laboratory.
Main duties and responsibilities
Investigate the isotopic fractionation of uranium during its abiotic reduction by ferrous iron Carry out experiments with seawater and variable organic carbon Collaborate with a senior microscopist to investigate reduction processes at the nanoscale Perform laboratory experiments Participate in general laboratory tasks Perform first-class scientific research Write publications Attend and present at international conferences. Profile
Educational background in geochemistry and preferably inorganic geochemistry Laboratory experience in geochemistry is a must Experience with natural isotopes desirable but not necessary Computer skills: Word, Excel, Powerpoint, some experience with at least one programming language Language: fluent English Self-motivation, scientific curiosity, critical thinking and rigor in experiment work, good communication skills and ability to work as part of an international team Enthusiasm, willingness to learn, good organizational skills We offer
An opportunity to develop a scientific career in environmental geochemistry an opportunity to learn high-end techniques and approaches The opportunity to build a scientific network in the field of geochemistry Excellent research conditions and competitive remuneration A multi-cultural and stimulating scientific environment Informations
