Our Work

The overarching goal of the IDDP Lab is to characterize neurobehavioral mechanisms that underlie the development and persistence of psychopathological behaviors, particularly externalizing and related behaviors (e.g., aggression, delinquency, substance use, psychopathy). Specifically, projects in our lab focus on the role of individual differences – with a specific focus on (dis)inhibitory and regulatory processes and other transdiagnostic social processes – as central mechanisms in the development of these problem behaviors. A secondary focus is on the dynamic interplay between and among these individual differences and various contextual factors that impact behavior. Our research with nonhuman primates affords the opportunity to undertake complex and innovative investigations that have clear translational value to humans.

Current Projects

Personality and Neuroscientific Indicators of (Dis)inhibitory and Regulatory Processes

Through this work, we aim to characterize transdiagnostic neurobehavioral mechanisms underlying externalizing and related behaviors. Current projects include, for example, examinations of differential associations between components of temperamental Disinhibition and executive functioning and various outcomes of interest (e.g., aggression, substance use, psychopathy). Additionally, we are currently working on studies examining neuroscientific and genomic correlates of psychopathology-relevant processes.

Trait Models of Personality and Neuroscientific Indicators of Personality PathologyaDSC_0337

We conceptualize personality pathology within a trait personality-based framework; thus, we consider personality pathology as a configuration of traits that differ from normality in degree rather than kind.  From this perspective, our research focuses on more fully understanding the neurobiological and evolutionary basis of personality in service of elucidating pathophysiological processes underlying both personality pathology and broader forms of psychopathology.
