I currently am Assistant Professor at DynFluid, a fluid dynamics laboratory part of ENSAM (École Nationale Supérieure des Arts et Métiers) in Paris, France. Recently, my research has been focusing on the use of Machine Learning and sparse regression techniques for the identification of nonlinear systems, with a particular emphasis on the SINDy algorithm by Brunton et al. (PNAS, 2016). The aim is to identify low-order models which can provide new insights into the physics of the flow considered or to be used for real-time feedback control.
