We conduct research to examine if findings from typical samples of individuals with sexual offences translate to incest offending. That is, sexual offences committed against related victims. We also investigate predictors of sexual behaviours between siblings, and what predict coercive sibling incest.
Current Research Focus
We are currently analyzing and writing papers intrafamilial sexual offending by fathers with a specific focus on the family dynamics that can facilitate or protect against sexual abuse by fathers. These studies included fathers from Brazil, Canada, India, Germany, and United States.
