Présentation

I am a senior research scientist at INRAE, Rennes, France, where I have been the ACTA group head since 2013. I received the PhD degree in 1999 in fluid mechanics from the Univ. of Poitiers, France. I work on experimental, numerical, and theoretical studies of turbulent flows, with applications in food, agriculture, and environment. My research is focused on turbulent shear flows by tackling crucial topics of measurements techniques, analysis and modeling of environmental and industrial flows in presence of non-canonical influences. This concerns the study of mixing layer/wake interaction, wake flow with spanwise non uniformity, mixing layer under the influence of thermal gradients, and mixing layer developing between non-uniform flows. Currently my research is mostly focused on developing and analyzing efficient models and methods for 2D and 3D spatiotemporal vector fields reconstruction from image sequences of turbulent flows. Key challenges are the development of observation and regularization models based on the physics of fluids, and the combination of image sequences with numerical simulation of dynamical laws.
