PhD position on Time-resolved Raman spectroscopy for investigating Mars habitability
Funding: three years.
The PhD student will be strongly involved in the setup and development of a timeresolved Raman spectrometer at IMPMC starting in the end of 2016. This equipment will be unique as it will allow bulk analyses (≈mm3) at distance in a Martian chamber (similarly to how SuperCam will operate on Mars) as well as analyses at the microscale (≈μm3) including Raman mapping. This combination will allow to improve the deconvolution of the signal analyzed at distance. The PhD student will (i) determine the optimal conditions for analyses (laser power, pulse duration, synchronization between the laser pulse and ICCD reading…) and to estimate accurately the detection limits; (ii) test the effect of Mars environment on Raman analyses by running measurements in the Martian chamber; (iii) analyze assemblages of organics and/or (micro)organisms with minerals to explore the capabilities of time-resolved Raman.
Altogether, this work will generate a unique and necessary scientific background and a spectroscopic database that will be critical for the preparation of the instrument in 2018 and the good operation of SuperCam in 2020. Coordination with LIBS will be done with IRAP Toulouse (P.-Y. Meslin) and SuperCam via S. Maurice (PI).
The PhD position opens in 2016. Candidates are invited to send a detailed CV with a letter of motivation to Olivier Beyssac (Olivier.Beyssac [at] upmc.fr) before the 15th of March 2016.
