PhD position in laser spectroscopy applied to astrochemistry, Paris-Saclay, France (Deadline: 30.08.2025)
A PhD position (funded by the Académie Spatiale d’Île-de-France) in laser spectroscopy applied to astrochemistry is available in the Jacovella group at the University of Paris-Saclay (France).
The experimental research involves ion mobility, mass spectrometry, and laser spectroscopy techniques applied to large carbon-rich molecular ions in the gas phase, in the context of astrochemistry and astrophysics.
Available equipment includes pulsed dye lasers and OPO laser systems, cavity ring-down spectroscopy (CRDS) coupled to a discharge source mounted at the exit of a molecular beam, an ablation laser source, and a drift-tube mobility spectrometer. A cryo-ion trap coupled to a time-of-flight (TOF) mass spectrometer is currently under construction. One project may also involve the development of a SLIM-based ion mobility spectrometer (all equipment available).
The group is also strongly involved in international collaborations with astronomers through various programs (PDR4ALL, EDIBLES, etc.), using different telescopes and facilities (JWST, VLT, OHP) and is a regular user of the SOLEIL synchrotron facility (France).
Qualified candidates should hold a Master’s degree in Physics, Physical Chemistry, or a related field.
The position is for 3 years, and the successful applicant may serve as a teaching assistant if interested.
Experience in several of the following areas is required:
– Laser spectroscopy, ion mobility, mass spectrometry, ion traps
– Vacuum systems, optics, data acquisition (Python preferred), construction of experimental apparatus
– Scientific writing (publications)
– Strong communication and presentation skills
Please provide a detailed CV (including a list of publications), a cover letter, and the names and contact details of two potential references.
The starting date for the PhD position is between October 1st and December 1st, 2025.
