Open Positions - Postdoctoral research associates

BASP is currently looking for an outstanding candidate for a postdoctoral position.


The Biomedical and Astronomical Signal Processing group (BASP) headed by Prof. Yves Wiaux at Heriot-Watt University is recruiting a postdoctoral Research Associate. The post-holder will perform cutting-edge research on compressive imaging algorithms, for application to, depending on candidate’s profile and interest, either ‘magnetic resonance fingerprinting in medicine’, or ‘radio-interferometric imaging in the SKA era in astronomy’.

The group is at the heart of a new research initiative on ‘Compressive Imaging in Astronomy and Medicine’. A multidisciplinary research team was recently created between Edinburgh, UCL London, and EPFL Lausanne to define new compressed sensing concepts for Fourier imaging applications, on both levels of data acquisition and image recovery, and validate them through numerical simulation and application to real data.

In medicine, our research targets ‘fast quantitative magnetic resonance imaging in the brain’. Fast high resolution imaging of quantitative tissue parameters can improve significantly the diagnosis of brain diseases in the future. The project will provide the first proof-of-principle for a new family of compressed quantitative magnetic resonance imaging schemes combining model-based compressed sensing with the recently proposed `Magnetic Resonance Fingerprinting’ acquisition philosophy.

In astronomy, our research targets `hyper-spectral radio-interferometric imaging’. The project is intended to provide, not only new sensing procedures dictating antenna configurations, but also a new generation of imaging algorithms and associated software that will give access to unprecedented resolution and sensitivity in the Big Data era of the forthcoming generation of telescopes such as the Square Kilometre Array (SKA).

The position advertised will be primarily weighted towards theoretical and simulation aspects of the project: Fourier sampling, enhanced signal models, convex/nonconvex recovery algorithms. Depending on the post-holder profile, it will tackle either the medical or the astronomical imaging application.

The post is initially available for 2 years.

Exact salary within scale 7 can be negotiated on experience and excellence criteria. Outstanding candidates may also be granted responsibility for co-supervising a BASP PhD student on a subject related to their research. They could also be considered for academic promotion within the School in the context of Heriot-Watt’s Global Platform Recruitment for Research Leaders.

For an expression of interest and to seek further information about the position please contact Prof. Wiaux directly by email.

Formal applications should be filled online on the Heriot-Watt University iRecruit System. You will also be requested to upload documents including a motivation letter, CV, publication list and reference names, preferably in a single pdf.

Screening of candidates will start in April 2016. Applications will be fully considered until the position is filled. The positions should start ideally on June 1, 2016.


Candidates must hold, or be about to finish a PhD in physics, astrophysics, MR physics, applied mathematics, computer science, electrical engineering, or a related area. Strong competence in signal processing is required, from inverse problems to image reconstruction algorithms, ideally with experience in either MR or radio-interferometric imaging.


The Biomedical and Astronomical Signal Processing group (BASP) is headed by Dr Yves Wiaux, Associate Professor in the School of Engineering and Physical Sciences at Heriot-Watt University in Edinburgh. Dr Wiaux is also Honorary fellow at the School of  Informatics of the University of Edinburgh, and Host Professor at the Signal Processing Laboratories of EPFL in Lausanne.

BASP is part of the Edinburgh Joint Research Institute in Signal and Image processing between Heriot-Watt University and the University of Edinburgh (JRI-SIP). The Joint Research Institute is a successful collaborative research venture exploiting complementary skills from the Institute for Digital Communications at the University of Edinburgh, and the Institute of Sensors, Signals and Systems at Heriot-Watt University. Formed in 2005, it offers a critical mass of more than 20 academic staff, supported by over 100 research staff and students, delivering world leading research and technology transfer in all areas of signal and image processing.

Open Positions - MSc/PhD Students

Applications from outstanding students are welcome for a MSc/PhD position with BASP.

Research topics include, but are not restricted to.

  • Fast, parallel and distributed compressive imaging algorithms (optimisation, Bayesian inference, high performance computing)
  • Theory of compressive imaging (signal models, reconstruction algorithms, Bayesian understanding)
  • Advanced signal processing for radio interferometric imaging in the context of SKA (dimensionality reduction, wide-band imaging, calibration)
  • Phase retrieval for optical interferometric imaging
  • Manifold compressed sensing for quantitative MR imaging (MR fingerprinting, brain microstructure mapping from diffusion MRI)
  • Advanced signal processing for quantum imaging (light-in-flight single-photon imaging, imaging around the corner)

For an expression of interest and details on the formal application process, please contact Dr Wiaux, by email to including your CV and a short motivation letter.
