A 24 months postdoctoral position is available from the 1st April 2022 at the Chemistry Department of Ecole Normale Supérieure (ENS, Paris). The project, funded by the European Innovation Council, relies on a collaboration between L. Jullien and T. Le Saux from the group «Physical and Biological Chemistry of Living Matter» at ENS with expertise in dynamic contrast fluorescence imaging, [1-5] and S. Matsubara and U. Rascher from the Institute of Bio- and Geosciences Plant Sciences (IBG-2) at Forschungszentrum Jülich (Jülich, Germany) with expertise in the time and space dynamics of photosynthesis in higher plants [6-7].

At ENS, the candidate will build an optical instrument that will provide harmonically modulated or randomly fluctuating illuminations while enabling remote fluorescence imaging of plants. This instrument will be eventually implemented in a greenhouse at IBG-2 in a purpose of extracting kinetic fingerprints devoted to sensing applications.

Starting date is flexible from 1st April 2022. Net salary: 2600-3000 €/month.

Candidates should hold a PhD in optics and have a solid background for building optical instruments and interfacing them for data acquisition. A former experience in fluorescence imaging and image analysis will be appreciated.

To apply, please send a detailed resume including list of publications, the names of at least two referees and a brief motivation letter to the scientific coordinators of the project, Dr. Thomas Le Saux (Thomas.LeSaux@ens.psl.eu) and Prof. Ludovic Jullien (Ludovic.Jullien@ens.psl.eu).
