Marlon Mundt is a health economist with multi-faceted expertise in primary care interventions, social networks, and substance use disorders. He has conducted economic analyses of tobacco and alcohol intervention in a multitude of populations and settings, including the NIAAA R01 projects TrEAT (AA08512), GOAL (AA08512), CHIPS (AA014685), and TAMI (AA12826) and the NCI P01 project BREATHE (CA180945). His work on the long-term efficacy and benefit-cost ratio of brief physician advice for problem drinkers in primary care, published in Alcoholism: Clinical and Experimental Research, has been cited over 728 times to date. The study findings were instrumental in the US Preventive Services Task Force recommendation that all adults be screened for problem alcohol use and that at-risk drinkers receive brief intervention counseling. In addition, he has been a co-investigator of the NIAAA R01 economic evaluation projects “Statistical Methods for Cost Research in Alcohol Studies” (AA12664, PI Dan Polsky) and “Costs and Benefits of Alcohol Services and Interventions” (AA13167, PI Michael French).
