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


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.
