Neuroengineering

My main interest is on the study of the principles of Neural Coding, especially for visual perception, memory, visuo-motor coordination and learning. This research involves the use and development of advanced methods of signal processing -such as wavelets, chaos theory, statistical mechanics and non-linear synchronization- for studying multiple single cell recordings, local field potentials and EEG signals.

Chemical sensing, UAVs

My research interest is in understanding the neuronal information processing underpinning olfaction (smell) and use this to build better machines to sense molecular stimuli (machine olfaction). How building models of sensory information processing helps us better understand the nervous system.

Electrocardiogram analysis

My current research interests are in real-time digital signal processing of biological signals, with particular interests in i) ECG analysis, including automatic arrhythmia monitoring, and heart rate variability analysis, and ii) microprocessor-, microcomputer- and Digital Signal Processor-based systems.

Neuroengineering

My main area of interest lies at the interface between Engineering and Neuroscience. I am particularly interested in developing and applying quantitative tools to help us understand how the brain works. My research involves the study of neural activity at very different scales, from single neurons to the study of macroscopic brain dynamics, using a variety of techniques: single-cell recordings in humans, Eye tracking, EEG and modelling.

Biomedical signal processing

After spending time in industry with BICC and Westinghouse I returned to teach Control Engineering at the University of Sussex. I was a Tutorial Fellow, a Lecturer and then a Reader at that University before transferring to Leicester as a Professor in 1985. I held a visiting position at the University of California at Berkeley. I was Head of the Department of Engineering at Leicester from 1988 to 1995.

Transducers

My interest in “dielectrics” as systems that respond to electric fields, extends to the biological systems.  In this area, I am interested in novel (typically optical fibre) sensing systems for patient monitoring and in developing systems (typical electrical stimulation systems) for assisting patients.

Dynamics modelling of cells and tissues

My research interest is in modelling of biological cells and tissues. Dynamic behaviour of these living systems reveals their health conditions. In particular, cancerous cells/tissues models of electrical impedance response indicate different parameter values to that of normal ones. Various modelling techniques are used in the research, including frequency domain and time domain identifications. 

High integrity, safety critical

My interest is in the development and verification of high-integrity systems: that is systems where very convincing arguments about behaviours are needed before those systems can be used and trusted.  The focus of this research is in the development and deployment of Formal Methods and Software Engineering techniques for the production of reliable software and reconfigurable hardware control systems.

Modelling degradation of bioresorbable polymers and devices

We have developed a complete mathematical framework to model the degradation of bioresorbable polymers and devices (including orthopaedic fixation devices, scaffolds for tissue engineering and devices for controlled drug release).

Control Engineering

I am a Control Engineer with research interests in robust control, optimization, linear parameter varying systems and industrial applications. I have been working on robust control theory such as robust gain-scheduling, robust tracking, fixed-order synthesis control within the Linear Matrix Inequality framework, applying some of this method to biological systems.

Reliable embedded systems

My main research interest is in the development of techniques and tools which support the design and implementation of reliable embedded systems. I am particularly interested in the links between software architecture and system reliability, and in the design of novel processor hardware. I am also interested in the links between software / hardware architectures and power consumption.  Recent applications of this work have included low-power medical monitoring systems.

Process modelling of pharmaceutical solid dosage forms

My main research interest is to develop a mechanistic understanding of powder and particulate processes with special focus on pharmaceutical solid dosage forms. The research is based on continuum mechanics and involves the development, calibration, implementation and practical use of advanced constitutive models for practical processing conditions encountered during granulation, particulate handling, compaction.
