Current Projects

Demography, Health, and Contraceptive Use of Repeat Teenage Mothers: This project uses national surveys, clinical data, and in-depth interviews to describe the population of teenage mothers who have more than one birth, their contraceptive use, and the processes by which they choose contraceptives. This information can be directly applied by health care professionals and policymakers in the design and implementation of programs offering effective contraception to prevent unintended births to teenage mothers. This project is funded by the National Institute on Child Health and Human Development.

Preventing Unplanned Repeat Births to Hispanic Adolescents: This project examines the prenatal predictors of postpartum long-acting reversible contraceptive (PPLARC) utilization among Latino teens, as well as the social and environmental influences on Latino teens’ contraceptive choices, in order to inform developmentally and culturally appropriate methods of preventing unplanned repeat births in this population. This project is funded by the William T. Grant Foundation Scholars Program.

Improving Maternal and Infant Health in Ecuador: This project focuses on wide-scale dissemination of Proyecto Telesalud an intervention we developed to deliver postpartum education and health support to mothers via cellular phone in Quito, Ecuador.

Sleep, the Adolescent Brain, and Risk Behavior: This project examines how sleep deprivation affects the adolescent brain and can lead to risky behavior such as substance use and risky sexual behavior, using a combination of survey, neuroimaging, and actigraphy methods. This project is funded by the National Institute on Drug Abuse.

Substance Use Brief Interventions in Adolescence: This project tests the feasibility of implementing universal drug and alcohol screening in high schools using the Screening, Brief Intervention, and Referral to Treatment (SBIRT) method. This work is funded by the Wisconsin Partnership Program.

Epidemiology and Etiology of Substance Use and Its Consequences
Using nationally representative data, an ongoing series of studies examines the epidemiology and etiology of adolescent substance use and its consequences.
