Kenneth E. Leonard, Ph.D., principal investigator on the study, is a senior research scientist at RIA as well as a research professor in the Department of Psychiatry in the UB School of Medicine and Biomedical Sciences. Since 1990, he has studied couples recruited while applying for marriage licenses at Buffalo City Hall.
Gregory G. Homish, Ph.D., RIA research associate, is Leonard's co-investigator. The research is funded by the National Institute on Alcohol Abuse and Alcoholism.
