A major research focus of the Biogeoscience Group in close synergy with the Laboratory of Ion Beam Physics is the development of analytical methods for the measurement of radiocarbon (C-14) using accelerator mass spectrometry (AMS). New information stemming from implementation of novel analytical capabilities opens up new frontiers of biogeochemical and paleoclimatological research.

Job description

The COMPASS project funded by the Swiss National Science Foundation aims at establishing and refining new methods that will enable novel C-14 applications through analysis at compound-specific and particle-specific levels. Such methods will allow components of well-defined origin to be isolated and isotopically characterized from complex, heterogeneous sediment matrices. During the 4 years of the PhD program, the PhD student will develop the use of novel analytical methods in compound-specific and particle-selective radiocarbon analysis (CSRA and PSRA, respectively), including sample processing by flow cytometry and micro-sublimation. Working in close collaboration with our project partners, these methods will be applied to selected well-characterized sediment cores in order to develop independent, proxy-specific C-14chronologies for sedimentary sequences. The PhD student will have the chance to learn state-of-the-art chemical and optical separation techniques and to perform measurements using Accelerator Mass Spectrometry (AMS). The student will have the opportunity to present results at national and international conferences. The successful candidate will be a member of the Biogeoscience Group (D-ERDW) and work in close collaboration with the Laboratory of Ion Beam Physics (D-PHYS).
