About the Project

The Biomedical and Astronomical Signal Processing group (BASP) at Heriot-Watt University Edinburgh (HWU), headed by Professor Yves Wiaux, is recruiting multiple PhD students for research on “AI algorithms for precision computational imaging”.

The BASP group is developing cutting-edge research on all aspects of computational imaging, from theory and algorithms, to applications in astronomy and medicine. Dr Wiaux is a Professor in the School of Engineering and Physical Sciences at HWU. He is also Honorary fellow at the School of Informatics of the University of Edinburgh (UoE), and Academic Guest at the Signal Processing Laboratories of the Ecole Polytechnique Fédérale de Lausanne (EPFL).

The positions are open in the context of large research projects funded by the UK research Councils, aiming to develop a new generation of computational imaging algorithms at the interface of deep learning and optimisation, simultaneously providing precision (i.e. enabling high resolution and dynamic range imaging), robustness (i.e. including calibration and uncertainty quantification functionalities), and scalability (i.e. able to handle unprecedented image sizes and data volumes). Firstly, algorithms will be designed for radio astronomy and validated beyond Terabyte image size, based on dedicated high performance computing implementations. Secondly, algorithms will be designed for both magnetic resonance imaging and ultrasound imaging in medicine, with more moderate image size requirements. The projects are led by Prof. Wiaux and supported by a unique team of international partners: Mr Jackson at the Edinburgh Parallel Computing Centre of UoE (EPCC), Prof. Pesquet from the Digital Vision Centre at Université Paris-Saclay (CentraleSupelec), Prof. Smirnov from the South African Radio Astronomy Observatory (SARAO), Dr Perley from the US National Radio Astronomy Observatory (NRAO), Dr Bouman and Prof. Hallinan from the California Institute of Technology (Caltech), Prof. Laing from the International Square Kilometre Array Organisation (SKAO), Prof. Thiran from the Signal Processing Laboratories of EPFL, Dr van Heeswijk from the Lausanne University Hospital, and Dr Buckley from Siemens Healthineers UK. A multi-disciplinary team of researchers is being recruited, spanning all aspects of the planned research, from theory to application.

PhD scholarships are available on any combination of the following facets of “AI algorithms for precision computational imaging”: (i) development of image estimation and uncertainty quantification algorithms for large-scale imaging inverse problems, at the interface of deep learning, optimisation, and Bayesian inference frameworks, (ii) their application in either astronomy or medicine (e.g. radio-astronomical, magnetic resonance, or ultrasound imaging), (iii) their parallel high performance computing implementation, as well as (iv) broader research projects within the field of “imaging and vision”.

We are looking for outstanding candidates with a First Class Master’s Degree in electrical engineering, applied mathematics, physics, computer science, or a related discipline. The PhD students will be fully integrated into BASP under the supervision of Prof. Wiaux, with possible co-supervision by project partners and beyond. The positions are initially for 36 to 42 months depending on the scholarship. The start date is to be agreed from September 2022.

Expressions of interest and other queries should be sent by email to Prof. Wiaux ([Email Address Removed]). Applications should consist of a single PDF (including a motivation letter, CV, publication list, and names of 3 references) and be submitted via the Heriot-Watt University website. The screening of candidates will start in January 2022, and continue until the positions are filled.
