LabEx LIO - Recrutement d'un post-doctorant sur DIAM « Dispositif d’irradiation de nanosystèmes biomoléculaires) - Duration: 2 years - Starting Date: Oct. 1st 2017

Job description:
Laboratory studies of the chemistry of planetary atmospheres and interstellar medium have historically focused primarily on small and simple molecules, such as benzene.
In more recent years, the attention has shifted towards larger molecules. Among them, a new place is reserved for nucleobases.
Nucleobases are N-heterocycles that are the informational subunits of DNA and RNA. They are divided into two molecular groups: pyrimidine bases (uracil, cytosine, and thymine) and purine bases (adenine and guanine). Nucleobases have been detected in meteorites, and their extraterrestrial origin confirmed by isotopic measurements. In particular, the fragmentation and dissociation pathways and the corresponding absolute cross sections are parameters that are of particular interest in this context.
This project will be devoted to the study of the fragmentation of complex molecules of prebiotic interest such as pyrimidine bases isolated in the gas phase or embedded in water nanodroplets in order to investigate radiation induced chemical reactions relevant to universe evolution.

The experimental method developed by the “Interaction Particules-Matière” (IPM) research group at the IPNL (Lyon, France) uses the DIAM, a device for irradiation of size selected molecular clusters. This device DIAM (Dispositif d’Irradiation d’Agrégats Moleculaires) is dedicated to the investigation of irradiation of nanosystems in the gas phase. It combines techniques used in ionising radiation physics, mass sprectrometry and high energy physics.

We are looking for a physician or chemist with expertise in mass spectrometry and/or ion beam physics. Competence in data analysis and/or unfolding methods would be also welcome, as would field or research experience on any experimental device in molecular or ion physics. The candidate should have a solid knowledge on radiation sciences and demonstrate excellent skills in data analysis (@Root environment)

The successful candidate (2 years) would be expected to:
1. Participate to experimental developments and data runs on the DIAM device at IPNL.
2. Analyze the resulting data in the @root environment.

Contact
Informal enquiries about the job and application process should be directed to Dr Bernadette Farizon: b.farizon@ipnl.in2p3.fr. Candidates should also send their applications to Dr Bernadette Farizon, including a curriculum vitae, list of publications and short statement detailing their research interests; and have two letters of recommendation sent directly to the same address.
We will continue to review applications until the post is filled. The anticipated starting date is Oct. 1st 2017.
