We have set up for the first time worldwide a measurement method for H2 clumped isotopes at natural isotopic composition, using the high-resolution mass spectrometer MAT-253 Ultra at IMAU. We are now looking for an outstanding candidate for further developing this work and applying these measurements to H2 from natural samples. This is a challenging but very rewarding project, and integrates elements of Physics, Chemistry, Geology and (Micro)Biology.

The work will start with setting up a method to extract H2 from (large) air samples. The H2 clumped isotopic composition will then be studied in samples from different environments, e.g. atmospheric air, anthropogenic sources, geologic and (micro)biologic emissions. The work will consist of lab experiments and measurements, and the candidate should be open for participation in field campaigns for sampling. 

The ideal candidate will have a good understanding of physical phenomena, good mathematical and logical thinking, and some experimental skills. Experience with trace gas or isotope measurements is useful, but not strictly necessary. More important are personal qualities like an open mind, enthusiasm, curiosity, creative thinking, ability to cooperate, and motivation. The position is meant for a PhD candidate, but exceptional candidates at Postdoctoral level are also considered.

We offer a temporary position (1.0 FTE) for four years. The research group will provide the candidate with necessary support on all aspects of the project. The gross monthly salary with a full time appointment will amount to €2,325 in the first year to €2,972 in the fourth year (P-scale of the Collective Labour Agreement Dutch Universities).

Salaries are supplemented with a holiday bonus of 8 % and a year-end bonus of 8.3 % per year. We offer a pension scheme, (partly paid) parental leave, collective insurance schemes and flexible employment conditions (multiple choice model).

A better future for everyone. This ambition motivates our scientists in executing their leading research and inspiring teaching. At Utrecht University, the various disciplines collaborate intensively towards major societal themes. Our focus is on Dynamics of Youth, Institutions for Open Societies, Life Sciences and Sustainability.

The Faculty of Science consists of six Departments: Biology, Pharmaceutical Sciences, Information and Computing Sciences, Physics and Astronomy, Chemistry and Mathematics. The Faculty is home to 6,500 students and nearly 1,500 staff and is internationally renowned for the quality of its research. The Faculty's academic programmes reflect developments in today's society. Read the overall impression 2016 of the Faculty of Science.

The Institute for Marine and Atmospheric Research Utrecht (IMAU) offers a unique research and teaching environment, in which the fundamentals of the climate system are studied. Research is organized in five themes: Atmospheric Dynamics, Atmospheric Physics and Chemistry, Coastal and Shelf Sea Dynamics, Ice and Climate and Oceans and Climate. In 2017, IMAU research quality and impact were qualified as 'world leading' by an international visitation committee. Currently, IMAU employs 15 faculty members and 10 support staff and some 20 Postdocs and 20 PhD candidates.
