Research Summary

As a clinical child and school psychologist, I am broadly interested in ways the principles of developmental psychopathology can be used to explore the impact of substance abuse on family process and the psychosocial development of children. I am particularly interested in (a) the impact of substance abuse on fathering, (b) parenting as a treatment issue for substance-abusing men and women, and (c) the development of parent intervention for men and women enrolled in substance abuse treatment.
