My research interests include

  • Cognitive psychopharmacology of addiction
  • The impact of addiction related behaviours (e.g. attentional bias, craving, expectancy) on non-drug seeking processes (e.g. reward motivation/value learning)
  • Models of psychological disorders, particularly in relation to abnormal beliefs (e.g. delusions) and reward dysfunction.
  • Effects of cannabinoids on human behaviour
  • 'New highs' such as 4-methylmehamphetamine (mephedrone)
