I am a behavioral health scientist with training in needs assessments, intervention development and evaluation. I joined the Johns Hopkins Center for American Indian Health in 2011 and currently manage studies focused on developing and evaluating interventions addressing sexual and reproductive health disparities (teen pregnancy, sexually transmitted infection) and diabetes among Native adolescents and young adults.

I am specifically interested in identifying how to leverage and engage families in youth focused programming and developing evidence to illustrate the utility and impact of including family members in youth programming. Currently, we are evaluating the impact of three programs that engage parents alongside their families to prevent teen pregnancy.
