Dr. Mellinger is an Associate Professor in Internal Medicine and Psychiatry at Henry Ford Health-Michigan State University where she practices clinically in general and transplant hepatology with a special focus on alcohol-related liver disease. She holds her medical degree from Northwestern University's Feinberg School of Medicine, and Masters' degrees in English Literature and History of Medicine from Oxford University (United Kingdom) and a Masters in Health and Healthcare Research from the University of Michigan. Her clinical practice and research focuses on the epidemiology of alcohol—related liver disease, cost-effectiveness of and access to alcohol use disorder treatments among those with ALD, and developing novel behavioral interventions to help patients with alcohol-related liver disease stop alcohol use and engage in alcohol treatment. Along with colleagues in psychiatry, in 2018 she founded the Michigan Alcohol Improvement Network's Multidisciplinary ALD clinic, one of the first fully integrated, co-located alcohol and liver disease treatment clinics for ALD patients in the United States. She is NIH-funded through the NIAAA and NIDA to study behavioral treatments in ALD.
