Research and expertise

  • Background and interests

    Research area of specialty:

    • understanding how altering sensory input from the spine and limbs affects sensorimotor integration and motor control
    • brain plasticity during virtual training in virtual reality (VR) including the role of altered sensory feedback in VR
    • altered sensory processing in chronic and recurrent pain 

    Techniques: electroencephalography (EEG), nerve stimulation, somatosensory evoked potential techniques (SEPs) to measure processing of sensory input by the brain, electromyography (EMG) to measure electrical activity in muscles, and transcranial magnetic stimulation (TMS) to investigate the output of the human motor cortex.
