Main Research Interests:
Current research interests are real-time digital signal processing of biological signals, with particular interests in i) ECG analysis, including electrical activation in Atrial Fibrillation, and heart rate variability analysis, and ii) microprocessor-, microcomputer- and Digital Signal Processor-based systems.
On ECG analysis the emphasis has been on signal processing of the electrical activation of the heart, especially the atria in Atrial Fibrillation, with Professor André Ng of Leicester General Hospital. 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 GPUs of graphics processor cards (with Dr. João Luiz Dihl Comba and Guilherme N. Oliveira of UFRGS, Brazil), Digital signal processors and personal computers, Assembly language (for the both DSP and the host PC), LabView, and C language. A full (but not very up-to-date...) list of my publications is at http://www.le.ac.uk/eg/fss1/publications.htm.
