    Research Interests

    My research addresses the development of callous-unemotional traits among children. Callous-unemotional traits (e.g., lack of remorse or guilt, lack of empathy) play an important role in designating a subtype of antisocial youths with a more severe and violent course of antisocial behavior than antisocial youths without these traits. Importantly, youths with callous-unemotional traits display similar cognitive, neurological and affective deficits that characterize adult psychopaths. However, we know little of how and when callous-unemotional traits develop in childhood or the early pathways linking these traits to later antisocial and aggressive behaviors. Consequently, the early development of callous-unemotional traits and their association with later antisocial and aggressive behaviors is the focus of my research
