Laurent Jacques received the B.Sc. in Physics, the M.Sc. in Mathematical Physics and the PhD in Mathematical Physics from the Université catholique de Louvain (UCL), Belgium. Postdoctoral researcher in the ICTEAM institute of UCL from 2005 to 2011, he was funded by the Walloon Region (2005-2006), the Belgian FRS-FNRS (2006-2010, 2011-2012) and by the Belgian Science Policy (Return Grant, BELSPO, 2010-2011). Visiting researcher at Rice University (DSP/ECE, Houston, TX, USA) in spring 2007, he also performed a postdoctoral stay from 2007 to 2009 at the Swiss Federal Institute of Technology (LTS2/EPFL, Switzerland). Since Oct. 2012, he is Professor and FNRS Research Associate in the Image and Signal Processing Group (ISPGroup) in ICTEAM/UCL. His research focuses on Sparse Representations of signals (1-D, 2-D, sphere), Compressive Sensing, 1-bit and Quantized Compressive Sensing, Compressive Imaging, Inverse Problems in Optics and in Computer Vision. Since 1999, Laurent Jacques has co-authored 29 papers in international journals, 45 conference proceedings and presentations in signal and image processing conferences, and 4 book chapters. Since 2015, L. Jacques is coordinating a Belgian Incentive Grant for Scientific Research MIS (AlterSense) on “Computational Sensing Strategies for Low-Complexity Signal Models”.

1.  Main fields of interest :

  • Inverse problems via Convex Optimization promoting a priori information (e.g. Sparsity).
  • Random projections (seen as dimensionality reduction) and Compressed Sensing.
  • Theoretical questions linked to new design of sensors (e.g. cameras, biosensors).
  • Applied mathematics for Astronomical and Biomedical signal processing questions.
