Research interests

The ethos of Prof. Wiaux’s Biomedical and Astronomical Signal Processing (BASP) group is is to develop cutting-edge research in computational imaging, from theory and algorithms to applications in astronomy and medicine.

In modern imaging applications, the next-generation algorithms devised to form images from observed data are required to deliver a new regime joint precision, robustness, and scalability. Our research spans multiple aspects of computational imaging,

  • from theory (inverse problems, sampling, dimensionality reduction, signal recovery, uncertainty quantification),
  • to algorithms (machine learning, convex / nonconvex optimisation, and Bayesian sampling),
  • to applications in astronomy (aperture synthesis in radio and optical astronomy),
  • to applications in medicine (magnetic resonance imaging, ultrasound imaging, novel imaging modalities),
  • also including the interface with high performance computing hardware and software technologies.


Prof. Wiaux received the MSc degree in Physics and the PhD 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 the Biomedical and Astronomical Signal Processing (BASP) group.

In 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 2016. He is also an Academic Guest at EPFL and an Honorary Fellow at the University of Edinburgh (UoE).

Among other reponsibilities, Prof. Wiaux chairs the BASP Frontiers Conference series, and is an Associate Editor of the Royal Astronomy Society Techniques and Instruments (RASTI) journal.

Since 2010, he has led numerous research projects funded by both the Swiss National Science Foundation (SNF) and the UK Research and Innovation Councils (UKRI).

The ethos of Prof. Wiaux’s BASP group is to develop cutting-edge research in computational imaging, from theory and algorithms to applications in astronomy and medicine.
