I currently have the following opennings:
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.

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.

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.
