Experiences & Accomplishments
Boston University
Tulane University
Tilburg University
I am a behavioral health scientist with training in needs assessments, intervention development and evaluation. I joined Johns Hopkins C in 2011 and currently co-direct all reproductive/sexual health focused studies at the Center for American Indian Health. These studies primarily focus on teen pregnancy prevention and STI/HIV prevention including access to STI self-administered screening and HIV self-administered testing.

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, I am leading the evaluation of a teen pregnancy prevention and substance use prevention program for young girls and their female caregivers- the strength-based program focuses on parent-child relationship and youth positive identity development.
