Responsibilities
Research within the SNF project "Carbon isotope fractionation during respiration: Mechanisms and environmental drivers" with focus on compound-specific isotope analysis using isotope ratio mass spectrometry (IRMS) and laser spectroscopy. Tasks include design and maintenance of experiments with plant seedlings in climate chambers, sample collection and preparation, isolation of plant compounds, ^13 C analysis with HPLC and GC coupled to IRMS, CO_2 flux measurements (photosynthesis and respiration), data analysis and interpretation, presentation of results nationally and internationally. Participation in further development of new methods for compound isolation as well as maintenance of instrumentation is expected. 

Requirements
Dynamic, reliable and motivated student with M.Sc./Diplom in plant ecophysiology, (bio)chemistry, ecology, environmental sciences or related disciplines. Strong interest in process-oriented research, particularly in plant physiology and isotope fractionating mechanisms.

Lab experiences and skills in working with HPLC/GC are beneficial.

English and German language skills are required. It is expected that the candidate will also collaborate with external institutes.

Additional benefits
The research will be carried out within a 3-year project, starting as soon as possible. We offer an interesting position in an international, interdisciplinary research group (www.gl.ethz.ch) at a lively university environment in Zurich as well as international working experiences. Measurements will be performed in cooperation with the PSI in Villigen (http://isotope.web.psi.ch). Salary and social benefits are provided according to ETH Zurich rules.

Application
Please send your complete application to Mr. Rolf Oertli, Human Resources, ETH Zurich, TUR C24, 8092 Zürich, mentioning "*IPAS-Isotope Biochemistry*". Evaluation procedure will start November 1^st , applications will be reviewed until the position is filled. Further information can be obtained from Mrs. C. Hostettler.
