Short biosketch


Lotfi Chaari received the engineering and master degrees from the High School of Telecommunication in Tunis (SUP'COM) in 2007. In 2010 he received the PhD degree from the university of Paris-Est. He prepared his PhD with the Signal and Communication group of the Laboratoire d'Informatique Gaspard Monge (LIGM), an associated lab of the Centre national de la Recherche Scientifique (UMR 8049 - CNRS). He has been working during his PhD on medical image reconstruction for Magnetic Resonance Imaging, in collaboration with NeuroSpin-CEA (Saclay, France), the first center in Europe dedicated to ultra-high field MRI and applications in cognitive neurosciences. He then moved to Grenoble as a postdoctoral fellow at Inria in the Mistis team where he worked on functional MRI data analysis and activation detection-estimation. Since september 2012, he is associate professor at INP-Toulouse. He is doing his research with the IRIT laboratory. In 2017, he received the HDR dissertation from the university of Toulouse. Dr Chaari's research field covers data reconstruction and restoration techniques under sparsity constraints, in application to medical imaging and remote sensing. He is also interested in variational, Bayesian and hybrid approaches for data analysis, classification and detection/estimation. Both model-based (inverse problems,...) and learning-based (machine learning, deep learning) techniques are developed.
