Main Research Interests:

Current research interests are 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.

On ECG analysis the emphasis has been on heart rate variability in asphyxia/hypoxia, with the collaboration with Prof. Nitish V. Thakor of The Johns Hopkins University, Baltimore and Dr. Mike Wailoo, from the Leicester Royal Infirmary and on atrial arrhythmias, with Dr. Andre Ng of Leicester General Hospital. Occasionally we dedicate attention to some non-Biomedical problem. One such system of interest is the diagnostic estimation techniques for vibration analysis in high speed rotating machinery. For the off-line aspects of the research we use either MATLAB programming, FORTRAN or C/C++, while for the real-time applications we use a set of hardware and programming tools that include Digital signal processors (AT&T DSP32C, TMS320C50 and the more modern TMSC6416 and TMSC6713), personal computers, Assembly language (for the both DSP and the host PC), LabView, and C language. A full list of my publications is at http://www.le.ac.uk/eg/fss1/publications.htm.
