Research interests

I am currently working on developing feasibility and pilot studies, and clustered randomised controlled trials.

Other research

My previous research has included

  • Time series analysis - in particular locally stationary wavelet processes.
  • Chronic ageing diseases - using longitudinal studies to identify single nucleotide polymorphisms associated type 2 diabetes and heart disease.
  • Animal behaviour - identifying environmental and behavioural characteristics associated with aggression in pigs.
