M.Sc. POSITION IN ENVIRONMENTAL CHEMISTRY
AT THE BEN-GURION UNIVERSITY OF THE NEGEV,
BEER-SHEVA, ISRAEL

One 2-year M.Sc. position is opened at the Marine Lab headed by Professor Alexey Kamyshny at the Ben-Gurion University of the Negev, Beer Sheva, Israel. The student will participate in project entitled Kinetics and Mechanisms Transformations of Volatile Organic Sulfur Compounds.

Dimethylpolysulfanes (DMPSs, H3C-Sn-CH3) are the products of biological and abiotic methylation of intermediates of hydrogen sulfur oxidation. These compounds have an unpleasant odor, which compromises the quality of drinking water. Pathways for the formation of these compounds in natural aquatic systems as well as rates and mechanisms of DMPSs decomposition reactions are poorly studied. The goal of this research is to understand the factors controlling concentrations of DMPSs in natural aquatic systems, rates of their formation and decomposition as well as terminal products of their decomposition.

Position includes research project as well as teaching assistantship. The total annual allowance (stipend and salary) is 46,000 NIS (~14,000$).

Project period: October 1, 2021 – September 30, 2023.

Application deadline: April 18, 2021

Please send application, including CV, transcript of courses with grades, application letter any additional relevant materials to Prof. Alexey Kamyshny: alexey93@gmail.com

Requirements:

  • B.Sc. in chemistry (preferred), earth sciences or environmental sciences with proven strong background in analytical and/or organic chemistry
  • average B.Sc. grade above 90 (or corresponding grade in other grading systems)
  • fluency in written and spoken English

Preferred qualifications:

  • hands-on expertise in chromatographic techniques
  • hands-on expertise in mass-spectrometric techniques
