Research interest

Research area


Physiological and psychological mechanisms in musculoskeletal disorders

My earlier research:

  • Estimating cumulative loading of the lumbar spine during occupational tasks using a posture matching technique
  • The efficacy of an ergonomics training and ergonomic chair provision on self reported and measured physiological variables amongst call centre workers: an intervention study
  • The effect of chair type and chair training on spinal loading during seated work
  • Development on a model to estimate lumbar spinal loads during cycling in masters level road racers
  • Work pace as a mediator of muscle activity levels in the trapezius muscle during light assembly
  • Quantification of methodologically induced error during EMG normalization in the upper trapezius muscle.

Current research interest


While at I am focusing on EMG data collection and processing strategies and will be working to provide clear guidelines for experimentally relevant normalization practices. I will bring together four studies that will quantify the amount of variance directly attributable to the methodological process of normalizing raw electromyography, compare the relative amount of induced variance across different normalization techniques, and will evaluate the quantitative importance of variance attributable to normalization in the context of biological and inter-subject variability.

I will then examine whether the interpretation of data can be affected by normalization method. This process will begin in the trapezius muscle, before migrating to the long erector spinae (ES) muscles.
