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 and imaging 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 RF sensing applications including dynamic MRI and 3D brain imaging, Electronic Surveillance and Low Frequency Synthetic Aperture Radar - work that is being exploited in a new DSTL funded Low Frequency SAR system with SEA Ltd. Most recently, in collaboration with colleagues at EPFL I have proposed a new compressed sensing framework for quantitative MRI.

I also have an active interest in the related topics of machine learning, high-dimensional statistics and information theory.

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
