Marissa A. Ehringer is Professor and Chair of the Department of Integrative Physiology at the University of Colorado Boulder, with a joint appointment at the Institute for Behavioral Genetics. Her research focuses on identifying genetic mechanisms underlying substance use disorders using genomics and bioinformatics approaches. She directs the Genetics of Substance Use Disorders Laboratory and mentors graduate trainees. Education: B.S. Biology & B.A. French, Indiana University (1995) Ph.D. Human Medical Genetics, University of Colorado Health Sciences Center (2001) Research Interests: Her work integrates behavioral genetics with genomic technologies to study alcohol, tobacco, and opioid use disorders. Key areas include: genetic epidemiology of addiction, neuropharmacology of substance responses, microbiome-gene interactions in opioid use disorder, and translational models of anxiety-related behaviors. Publications: Recent articles demonstrate strong focus on opioid genetics (33%), anxiety mechanisms (25%), diversity/inclusion in genomics (17%), and translational rodent models (25%). Methodological emphasis includes GWAS, transcriptomics, and microbiome analyses. Honors: NIH Training Fellowships (NIMH, NIDA) Leadership positions: RSA Board Member, IBNGS President Faculty Leadership Institute Fellow UROP Outstanding Mentor Award Training & Grants: Currently advises 6 graduate students. Active NIH grants include: U01 DA051937 (genetic networks in opioid disorder), R21 DA05781 (glial role in nicotine behaviors), and AB Nexus award (GCKR variant effects).
