Imaging Data in Emerging Adults with Addiction (IDEAA) is a multi-site consortium  which combines common, overlapping neuroimaging and behavioral measures in cannabis-using subjects and healthy controls across a broad and overlapping age

range (16-25) for multiple NIH/NIDA-funded sites across the country.

This consortium was conceptualized by Dr. Gruber and collaborator,

Dr. Krista Lisdahl, who have joined forces with Dr. Susan Tapert and

Dr. Francesca Filbey. Neuroimaging (structural, resting state fMRI, and diffusion tensor imaging), neurocognitive, clinical, and drug-use data from over 600 participants will be collected at multiple sites across the U.S. and will be pooled in order to create the largest sample of well-characterized emerging adult marijuana users and matched controls to date.

Dr. Gruber serves as the McLean-site PI in the IDEAA consortium. Her clinical and research focus is the application of neurocognitive models and multimodal brain imaging to better characterize neurobiological risk factors for substance abuse and psychopathology. Dr. Gruber’s lab has examined the etiologic bases of neural models of dysfunction in patients with psychiatric disorders as well as cannabis-abusing adults. She is involved in the application of behavioral science to help shape policies regarding juvenile advocacy. Dr. Gruber also directs the MIND program, designed to clarify the effects of medical cannabis on brain structure, function, and quality of life.

Dr. Lisdahl serves as the UWM-site PI in the IDEAA consortium. She is also the director of the Brain Imaging and Neuropsychology (BraIN) Laboratory at UW-Milwaukee.  Her research focus is on the neurocognitive consequences of chronic drug use during adolescence and young adulthood. More specifically, using magnetic resonance imaging (structural MRI, functional MRI and diffusion tensor imaging) and neuropsychological assessment, she examines the effects of marijuana, alcohol, nicotine and ecstasy on brain structure and function. Her lab also attempts to explain individual differences by examining whether gender, genetics, or lifestyle factors moderate these effects. 
Professor of Psychiatry, University of California, San Diego

Dr. Tapert serves as the UCSD-site PI in the IDEAA consortium. Her research focuses on understanding neural sequelae of and risk factors for adolescent substance use. Her work uses magnetic resonance imaging (MRI), functional MRI, diffusion tensor imaging, and neuropsychological testing. Her studies evaluate adolescent brain development and sex differences.
Associate Professor, University of Texas at Dallas

Dr. Filbey serves as the UTD-site PI in the IDEAA consortium. Her research interests are focused on combining neuroimaging and genetic techniques to characterize neural mechanisms associated with addictive disorders. Specifically, she is interested in how environmental factors (e.g., adolescent onset of use, early life stress) mediate the neural mechanisms that are associated with addictive disorders and how genetic risk moderates these effects. Her current projects involve the determination of these effects using neuroimaging tools and a candidate gene approach in marijuana and tobacco users in addition to obese binge eaters.
