Telecommunications: synchronization and end-to-end timing transfer in networks including satellite networks, jitter; Metastability. Signal processing, especially nonlinear signal processing in a range of application areas: Biomedical: blind deconvolution to recover MUAP from EMG signals, inverse filtering to recover firing patterns; Speech: deconvolution and inverse filtering to recover glottal source, glottal source modelling and analysis; Music: polyphonic music transcription, polyphonic pitch detection, onset detection; Higher Order Statistics, especially bispectrum;
