The Early Growth and Development Study Pediatric Cohort
UH3 OD023389 (PI: Leve) 09/01/18-08/31/21
Office of the Director, NIH
This Pediatric Cohort of the Environmental Influences on Child Health Outcomes (ECHO) initiative leverages and builds upon a unique existing “dual-family” adoption design to isolate early environmental exposures from heritable influences on familial clustering of health problems to contribute to ECHO’s overall goal of investigating the role of early life exposures and underlying biological mechanisms in childhood health and disease.

Bio-behavioral developmental origins of adolescent substance use
K01 DA039288 (PI: Marceau) 03/01/16-02/28/21
NIDA
The goals of this K01 are to improve our understanding of how multiple biological (genetic, hormone) and environmental (prenatal exposures and parenting) influences work together for the development of adolescent substance use and to prepare the Candidate for an independent career as an interdisciplinary, developmental scientist. The work conducted here will lead to better targets for prevention efforts by helping to identify the strongest predictors given multiple other influences and constructing more specific profiles of risk for determining which individuals are likely to initiate early.

The role of substance use trajectory on the association between childhood maltreatment and intimate partner violence: a gene-environment study
R36 DA047563 (PI: Mishra, Mentor: Marceau) 07/01/19-08/31/20
NIDA
This study will evaluate the role of developmental trajectories of substance use for the association between childhood maltreatment exposures and inter-personal violence in adulthood, and whether genetic risk for substance use strengthens this developmental pathway. Understanding the roles of substance use and associated biological underpinnings for the maltreatment-violence cycle will provide critical avenues for the prevention of these associations in future generations.

Adolescent substance use: Indiana community needs and education through extension
Purpose: The primary goal of this study is to facilitate informed decision-making to improve the well-being of Indiana youth and their families. The project involves 1) information gathering, 2) an outreach component: education through Extension, and 3) qualitative community-based participatory research aimed at understanding the prevalence of adolescence substance use and needs of Indiana residents surrounding adolescent substance use prevention and resources.
Sample: 1) 200 parents of adolescents in Indiana and 87 Indiana Extension Educators; 2) ~20 Extension Educators; 3) participants of Extension Programming in participating counties.
Funding: Purdue’s AgSEED program (PI: Marceau)
Real-time Salivary Testosterone and extension to mobile Application and Multiple Biomarker Quantification Capability
Purpose: This Small Business Innovation Research Award (SBIR) will develop a new device to assay salivary testosterone in real-time. This device will be more cost effective and faster than current assay techniques, with both research and point-of-care applications. My role is as statistical consultant in order to confirm the validity of testosterone levels recovered by the new device in comparison to current gold-standard salivary testosterone assays.
Funding: National Institute on Drug Abuse: R34 DA043293 (PI: Slowey) 07/15/18-07/14/19. Dr. Marceau was a consultant on this grant.
