Research interests

Marion's research interests encompass the sociology of punishment, criminal law, and human rights. Her book, Normalising Punishment: the case of life without parole in California has been published by Oxford University Press in 2021.

Marion continues to be interested in topics relating to life imprisonment and the politics of punishment more broadly. Her other research inquiries include ageing, gender, and migration studies.
