Dr. Lipton's interests center on two general areas: Alcohol and health and geographical-spatial methods of assessing public health issues such as violence and alcohol outlets. For the former, he has received NIAAA funding to examine abstention, alcohol consumption and health. For the latter, he has received funding from the state of California to investigate the spatial relationships of underage drinking in the City of Los Angeles, and tobacco-related disease throughout the state. In addition, he has NIAAA funding to study drug market activity, alcohol outlets and violence in Boston, Massachusetts. He also has worked on mathematical and statistical models related to alcohol consumption assessment. He additionally works on the ways in which causal thinking is used and misused in epidemiology. Dr. Lipton co-leads the Center's activities for Methods.
