post doctorat at PMMH (M/F)

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description The postdoctoral researcher will study in detail the heteroaggregation of microplastics with microorganisms in flows, quantifying the effect of microorganisms and hydrodynamic conditions on biofilm development and on the structure of the resulting aggregates. This work will rely on a microfluidic and acoustofluidic platform under development in the laboratory, enabling the culture, observation, and contactless manipulation of these objects. Particular attention will be paid to the biological composition and properties of the biofilms. • Setting up and optimizing experimental protocols: culture of microorganisms (bacteria, micro-algae) under microfluidic flow, preparation and characterization of model microplastic suspensions. • Performing heteroaggregation experiments and monitoring biofilm formation by optical and fluorescence microscopy. • Analyzing and quantifying biofilm structure and growth (imaging, image analysis). • Analyzing the expression of target genes (RT-qPCR) as a function of culture conditions (flow, presence of microplastics). • Data analysis, writing scientific publications, and presenting results at conferences. • Contributing to supervision and to the scientific life of the laboratory. The postdoctoral researcher will be hosted at the PMMH laboratory (Physique et Mécanique des Milieux Hétérogènes, UMR 7636 CNRS–ESPCI–PSL–Sorbonne Université–Université Paris Cité)
