A postdoctoral position in Analytical Chemistry/Environmental Chemistry is open in the Institute of Chemistry from the University of Campinas (UNICAMP), in collaboration with the Brazilian Synchrotron Light Laboratory (Campinas, Brazil).

Duration: 1 year

Starting date: 1 February 2021 or later

Deadline for application: November 30th 2020

The proposal aims to elucidate the functioning of two cyanobacteria in relation to arsenic speciation, bioaccumulation and biotransformation in alkaline-saline lagoons in the Pantanal (Brazil) that present high concentrations of As (up to 3 mg / L), and thus to better understand the role of these microorganisms in the biogeochemical cycle of As in this ecosystem. To achieve this goal, two cyanobacteria (Arthrospira sp. And Anabaenopsis sp.) already isolated will be grown in medium enriched with As (III) / As (V). The different types of samples (culture medium and cells) will be analyzed using a combination of different analytical techniques: HPLC-UV -HG-AFS, LC-Electrospray-MS / MS and synchrotron radiation produced by a fourth generation source. Synchrotron radiation analysis will be carried out on the CARNAÚBA beamline (Coherent X-rAy NAnoprobe BeAmline) in the new synchrotron light source at the National Synchrotron Light Laboratory (LNLS), Sirius. The cultivation of cyanobacteria will be carried out at the Cellular and Molecular Biology Laboratory of CENA / USP.

Required Skills: The candidate must have:

1) Experience in analysis by synchrotron radiation (XRF, XAS), 2) Experience in Analytical Chemistry in particular with techniques such as HPLC-HG-AFS, HPLC-MS/MS, LC-Electrospray-MS/MS, 3) practical knowledge in sample preparation. The integration of the postdoctoral fellowwith the project researchers is also desirable. The candidate should have concluded a doctorate less than seven years before the beginning of the PD fellowship.

This opportunity is open to candidates of any nationalities. The selected candidate will receive a Post-Doctoral fellowship from the São Paulo Research Foundation (FAPESP) in the amount of R$ 7,373.10 monthly and a research contingency fund, equivalent to 15% of the annual value of the fellowship which should be spent in items directly related to the research activity.

Contact: Interested applicants should submit by email to Prof. Anne Helene Fostier ( a Motivation Letter; 2 reference letters; a short CV (1-2 pages) emphasizing the skills required in the project; summary of the PhD thesis.
