Ms Martine Skumlien University positionPhD student DepartmentsResearch ThemeInterestsMy research is focused on understanding the association between cannabis use and reward processing, including anhedonia and apathy. I am especially interested in whether adolescents show greater vulnerability to putative harmful effects of cannabis compared with adults. Most of my PhD data come from the UCL CannTeen study (https://www.ucl.ac.uk/psychopharmacology/trials/cannteen). I use experimental as well as observational designs with methods including surveys, laboratory tasks, and fMRI. Research Focus
