postdoc positions are available to work at the Institute of Physics, Rennes, France,
Up to two postdoc positions are available to work at the Institute of Physics, Rennes, France, on the ERC Advanced Grant Project CRESUCHIRP
Applications are invited for postdoctoral research associate positions at the Institute of Physics Rennes (IPR) to conduct experimental research in fundamental chemical physics and reaction kinetics, with particular application to molecular astrophysics and astrochemistry. The project, supported by the European Research Council (ERC Advanced Grant to Ian Sims, Acronym CRESUCHIRP), aims to develop a combination of a chirped-pulse (sub)mm-wave rotational spectrometer with uniform supersonic flows generated by expansion of gases through Laval nozzles and apply it to problems at the frontiers of reaction kinetics.
The CRESU (Reaction Kinetics in Uniform Supersonic Flow) technique, combined with laser photochemical methods, has been applied with great success to perform research in gas-phase chemical kinetics at low temperatures, of particular interest for astrochemistry and cold planetary atmospheres. Recently, we have been involved in a collaboration with Arthur Suits (U. Missouri) and Bob Field (MIT) to develop a new combination of the revolutionary chirped pulse broadband rotational spectroscopy technique invented by Brooks Pate and co-workers with a novel pulsed CRESU, which we have called Chirped Pulse in Uniform Flow (CPUF). We propose to exploit the exceptional quality of the Rennes CRESU flows to build an improved CPUF instrument, and use it for the quantitative determination of product branching ratios in elementary chemical reactions over a wide temperature range (data which are sorely lacking as input to models of gas-phase chemical environments), as well as the detection of reactive intermediates and the testing of modern reaction kinetics theory.
The successful candidate(s) will work closely with Ian Sims and the CRESUCHIRP team at the IPR (including Abdessamad Benidar, Ludovic Biennier, Robert Georges and Sébastien Le Picard) as well as a team of internationally renowned external experts. The project is fully funded by the ERC as well as the Brittany Region and Rennes Metropole, and benefits from new, dedicated laboratory and office space.
The positions are available immediately (initially for 12 months, renewable for two further periods of 12 months by mutual agreement) and a competitive salary will be offered. Candidates should possess a PhD in experimental physics or physical chemistry, and experience in the use of microwave spectroscopy, pulsed lasers, vacuum and gas handling techniques and computer interfacing and programming are highly desirable. Experience in supervision of research (e.g. undergraduate projects) would also be advantageous. Knowledge of the French language, while advantageous, is not essential, and language lessons can be arranged if desired.
Inquires and applications, including a detailed CV citing grades, a letter of intent, and the names and contact details of three potential referees, should be addressed to Prof. Ian Sims (firstname.lastname@example.org). Review of candidatures will begin immediately, and the call will remain open until suitable candidates have been appointed.

Research Fellow in Astrochemistry
Are you an ambitious researcher looking for your next challenge? Do you have an established background in experimental chemical kinetics, reaction dynamics, photochemistry or astrochemistry? Do you want to further your career in one of the UK’s leading research intensive universities?
We are looking for an exceptional researcher to work on our project ‘Astrochemistry of old stars: direct probing of unique chemical laboratories (AEROSOL)’, with Professors Dwayne Heardand John Plane. This interdisciplinary project on the stellar winds around evolved stars is funded by the ERC Consolidator Grant AEROSOL(Principal Investigator: Professor Leen Decin, University of Leuven). The aim of the project is to boost our understanding of the physics and chemistry characterizing the stellar winds around evolved stars. The project builds upon novel observations, detailed theoretical wind models, and targeted laboratory experiments.
Our experimental research concerns the determination of rate coefficients and product distributions of elementary gas-phase reactions involving key reactive species (OH, C2H, HCHO, etc.) in stellar winds for which data are currently lacking. Specifically, several advanced laser-spectroscopic and chemiluminescence techniques will be employed to follow photolytically-generated reactive species in real time in a state-of-the-art low-temperature Laval-nozzle apparatus, and also other apparatus, with the aim to obtain the rates of gas-phase reactions at temperatures below 200K.
You will perform research on the AEROSOL project, working in collaboration with a team of astrophysicists, chemists and computational mathematicians in both Leeds and Leuven. You will also have opportunities for training in science and people management, science communication, and grant application writing, with the aim to develop a personal independent career track.
You will have a PhD in Astrochemistry, Astrophysics, Physical Chemistry or a closely aligned discipline, together with experience in laboratory studies of chemical kinetics, reaction dynamics or photochemistry. You’ll also have excellent communication skills and the ability to work under pressure and meet deadlines.
There is also a potential opportunity for you to be employed and funded by Leuven University, Belgium, for a subsequent one year period following the two year appointment at Leeds. Both Universities have modern and fully equipped research laboratories, and both groups enjoy and encourage further close collaboration with researchers in departments employing high-level quantum chemical calculations on species related to this project.
