Current Research Support

NIDA R01 (050346) Testing a Developmental Model of Conduct Problems09/01/07 - 8/31/12 (P.I. S. Rhee)
To test the developmental propensity model and alternative examining very early predictors of early-onset conduct problems and related disruptive behavior disorders.
Role: Co-Investigator

NIDA R01 (012845)Genetics of Adolescent Antisocial Drug Dependence (COMRAD) 07/15/08 - 12/31/12
(P.I. J. Hewitt) To continue a multisite collaboration to conduct a prospective study to address critical issues in the genetic epidemiology of adolescent onset antisocial drug dependence. We will complete five year follow-up assessments, examine drug use and antisocial behavior trajectories and their predictors, and we will conduct genome wide association analyses of persistent adolescent-onset antisocial drug dependence.
Role: Co-Investigator

NIMH P50 (079485) Determinants of Executive Function and Dysfunction04/22/08 - 01/31/13
P.I. M. Banich; subcontract to Hewitt) Genetic Mechanisms of Executive Functions
The goal of this project is to use molecular genetic analyses in concert with computational modeling to begin to specify in more detail how the dopamine system regulates three correlated but separable executive functions - inhibiting prepotent response, updating working memory, and shifting mental sets.
Role: Co-Investigator

NIMH R01 (063207) Executive Functions and Self-Regulation: A Twin Study09/01/08 - 05/31/12
(P.I. Hewitt) This twin study will assess, during the transition from adolescence to young adulthood, genetic and environmental contributions to stability and change in executive functioning, individual differences in self-regulation; and the relationships between executive functions and self-regulation.
Role: Co-Investigator

NIDA P60 (011015) Antisocial Drug Dependence: Genetics of HIV Risk Behaviors 05/01/09 - 02/28/14
(P.I. J. Hewitt)
The overall goal of this P60 Center is to contribute to our understanding of the etiology of individual differences in behavioral disinhibition, the its relationship to drug abuse dependence, and the role that these play in the propensity for risky behaviors that may result in STDs, including HIV/AIDS.

Component 3: A Neurogenetic Basis for Risky HIV-Related Decisions(P.I. T. Crowley; subcontract to Young)
We will conduct brain imaging studies to explore a neural basis for risky behaviors in disinhibited individuals; estimate the heritability of CBG performance and its relationship to behavioral disinhibition and HIV risk behaviors; examine SNPs associated with behavioral disinhibition in relation to brain ROIs.
Role: Co-Investigator

NIAAA R01 (016960) Understanding Alcohol Misuse, Abuse and Dependence in Young Adulthood 01/01/09 to 12/31/11 (P.I. K. Hill; Subcontract to M. McQueen)Gene-Environment Interactions
This study seeks to explain the occurrence and course of binge drinking, alcohol abuse and alcohol dependence in young adulthood in the Seattle Social Development Project panel, which is aa theory-driven, longitudinal study of child and adolescent predictors of health and behavior problems and prosocial development.
Role: Co-Investigator
