Dr Troup is a Reader in Psychology, Clinical and Cognitive Neuroscience, at University of the West of Scotland. Her research focus is on the effects of cannabis on brain and behaviour in both medical and recreational cannabis use. Much of this work is centred around emotion processing in cannabis users using Event Related Potentials to better understand the endogenous and exogenous variables that influence emotional expression recognition. Currently the main emphasis of her research is to understand how Cannabis effects emotion processing in particular in relation to emotion processing disorders such as depression, anxiety and PTSD. Central to this is understanding the effects of cannabis in an ecologically valid model of both recreational and medicinal applications in both clinical and non-clinical populations. Her work is both theoretical and applied emphasizing the importance of developing fact-based scientific support for arguments for and against cannabis exposure.
