Post Doctoral Researchers in Computational Sensing and Machine Learning

Two postdoctoral research associate positions for 24 months in the first instance are available to work with Professor Mike Davies and his team on the ERC Advanced grant project, C-SENSE (Exploiting Low Dimensional Models in Sensing, Computation and Processing). This project aims to make theoretical and algorithmic advances in the use of low dimensional data models for sensing, signal processing and machine learning to reduce computational, storage and acquisition costs.

The post holders will develop a framework to exploit novel compact representations of signals and data and explore the theoretical and algorithmic interplay between signal structure, computational cost and statistical accuracy.

PhD studentship in Compressive Learning 

This project will develop and analyze new algorithms for compressive learning and investigate their computational and statistical efficiency in processing big data. The studentship forms a key component of the advanced ERC project C-SENSE, "Exploiting Low Dimensional Models in Sensing, Computation and Processing".

Biography

Career History

Mike Davies holds the Jeffrey Collins Chair in Signal and Image Processing at the University of Edinburgh where he leads the Edinburgh Compressed Sensing Research Group. He was Head of the Institute for Digital Communications (IDCom) in the School of Engineering 2013-16 and Director of the Joint Research Institute in Signal and Image Processing (JRI-SIP) a the collaborative research venture between the University of Edinburgh and Heriot-Watt University as part of the Edinburgh Research Partnership.

He received an M.A. in engineering from Cambridge University in 1989 where he was awarded a Foundation Scholarship (1987), and a Ph.D. degree in nonlinear dynamics and signal processing from University College London (UCL) in 1993. In 1993 he was awarded a Royal Society University Research Fellowship. He currently manages a £7M portfolio of research grants from a variety of sources including: EPSRC, Dstl, industry, EU and the ERC, and leads the University Defence Research Collaboration (UDRC), a UK programme of signal processing research in defence in collaboration with the UK Defence Science and Technology Laboratory (Dstl).

Research Interests

My work focusses on the fields of sparse representations and compressed sensing, and their application to various signal processing, imaging and machine learning problems. During the past decade I have made significant contributions to the key areas of fundamental CS theory, new signal models, including dictionary learning techniques, the development and analysis of new reconstruction algorithms, This work includes: the proposal and analysis of the highly popular Iterative Hard Thresholding family of algorithms for sparse reconstruction; the development of new reconstruction theory for structured sparse signal models; the introduction and analysis for a new model (co-sparsity) for redundant analysis representations; and the characterization of types of statistical distribution that admit accurate low dimensional approximations.

I have applied these ideas to a number of applications including: chemical identification in Raman spectroscopy, dynamic MRI and 3D brain imaging, a new compressed sensing framework for quantitative MRI, electronic surveillance and Synthetic Aperture Radar.

Current Projects

ERC Advanced Grant: C-SENSE, "Exploiting Low Dimensional Models in Sensing, Computation and Processing"

The aim of this project is to develop the next generation of compressive and computational sensing and processing techniques.

UDRC: University Defence Research Collaboration in Signal Processing

An academia led partnership between the defence industry, academia and the government sector. The UDRC develops research in signal processing with application to the defence industry.

CQ-MRI: EPSRC funded award in Compressed Quantitative MRI

The proposed research will provide the first proof-of-principle for a new family of Compressed Quantitative Magnetic Resonance Imaging (CQ-MRI), able to rapidly acquire a multitude of physical parameter maps for the imaged tissue from a single scan.

CIRI: EPSRC funded award in Compressed Imaging in Radio Interferometry

The CIRI project aims to bring new advances for interferometric imaging for next-generation radio telescopes, together with theoretical and algorithmic evolutions in generic compressive imaging.

EU Innovative Training Networks:

SpaRTaN: Sparse Representations and Compressed Sensing Training Network

MacSeNet: Machine Sensing Training Network
