Missions

A full-time post-doctoral researcher position is open at the Chemistry Group of Condensed Matter Physics Lab (Laboratoire de Physique de la Matière Condensée - LPMC) at Ecole Polytechnique, led by Dr. Thierry Gacoin & Dr. Jongwook Kim (jong-wook.kim@polytechnique.edu). The position is funded by the french National Research Agency (ANR). The position is funded for one year and renewable for the second year depending on performance, employment authorization, and mutual agreement. The annual salary bases on the table of CNRS – Ecole Polytechnique.

Scientific project:
We have been developing anisotropic nanocrystal phosphors that can be used as orientation probes. They have versatile uses, for instance, to track complex motion of motor-proteins, to analyze self-assembly of colloids, and to monitor dynamic flow profiles in microfluidic devices. The latter exploits the tendency of rod-shaped nanocrystals orienting under flow-shear, on which we established a 3D tomographic microflow imaging. Currently we are running a project applying this technique on cellular bio-fluidics, and launching a new government-funded (ANR) project tackling the issue of 'sustainable energy' by implementing an in-situ microfluidic-and-electrochemical analysis in kinetic energy harvesting devices.

Activities

The main activity of the position is to chemically synthesize nanocrystals with anisotropic luminescence property, and develop diverse application methods and devices. The expertise in nanocrystal synthesis, colloid science, TEM, and optical spectroscopy is welcomed. The aim of the project is to understand and finely control directional optical properties arising from the structural anisotropy of nanocrystals and their assemblies. The main application areas are biomedical analysis and energy-saving devices. The main tasks of the position are:

1) Chemical synthesis of lanthanide-doped nanocrystals with anisotropic structure and emission properties
2) Surface functionalization of nanocrystals for their dispersion in various media for applications
3) Polarization-resolved confocal-micro-spectroscopy of organized or single nanocrystals
4) Basic characterization of nanocrystals (TEM, SEM, XRD, Fluorescence spectroscopy)
5) Applications in micro-fluidic systems

Skills

The candidate should hold a PhD in chemistry, physics, materials science or a discipline relevant to the theme of the project, with a profound experience. The experience in nanocrystal chemistry is essential. Additional expertise in photo-physics and spectroscopy of lanthanide luminescence is welcomed.

Application should include a CV, a list of publications, a motivation letter, and the names/contact details of references.

Work Context

PMC is one of the 22 laboratories located at the Ecole polytechnique research center working on the frontier of knowledge on the major interdisciplinary scientific, technological and societal issues. Within the Teaching and Research Department of Ecole polytechnique, PMC (Laboratoire de Physique de la Matière Condensée) is a mixed research unit (Ecole polytechnique/CNRS) whose work is organized around two fundamental topics that are the nanosciences and the physics of Irregularity. We try to understand the solid, liquid or intermediate states (gel, pastes, foams…) of matter (structure, properties, phenomena of sets related to the interactions between the particles that compose it), the condensed matter physics is a science that is upstream of innumerable technological advances.
