Personal profile

Research interests

  • Theory - inverse problems, sampling, dimensionality reduction, signal recovery, uncertainty quantification
  • Algorithms : convex/nonconvex optimisation, Bayesian inference, greedy algorithms
  • Biomedical imaging Applications - magnetic resonance imaging, ultrasound imaging, novel imaging modalities, etc.
  • Astrophysics - imaging techniques in radio and optical astronomy, data analysis.


Prof. Wiaux received the M.S. degree in Physics and the Ph.D. degree in Theoretical Physics from the Université catholique de Louvain (UCL, Louvain-la-Neuve) in Belgium, in 1999 and 2002 respectively. He was a Senior Researcher at the Signal Processing Laboratories of the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland from 2003 to 2013, where he created and ran the Biomedical and Astronomical Signal Processing (BASP) group.

In fall 2013 he moved as an Associate Professor at the School of Engineering and Physical Sciences of Heriot-Watt University where he currently runs the BASP group. He was promoted to Professor at Heriot-Watt in Summer 2016. He is also an Academic Guest at EPFL and an Honorary Fellow at the University of Edinburgh.
