  • Electromyographic activity of the human genioglossus (EMGgg) muscle during wakefulness and sleep
  • Invivo size and shape measurement of the upper airway using endoscopic optical coherence tomography
  • Mechanism of reflux in obstructive sleep apnoea
  • Modulation of upper and lower oesophageal sphincter tone during sleep
  • Non-invasive acoustic detection of aerophagia sounds during wakefulness, anaesthesia and sleep
