Dvora has a PhD degree in molecular genetics from the Rockefeller University, where she studied the epidemiology and genetic basis of complex metabolic disorders. She continued with post-doctoral training at Columbia University, focusing on statistical methods for analyzing genetic risk factors for complex disorders. Then, she became an Assistant Professor at Columbia University and a Research Scientist at the New York State Psychiatric Institute. The focus of her research was the epidemiology of and risk factors for substance use and substance use disorders in general population and clinical samples. Main projects included identifying genetic and environmental factors underlying nicotine and alcohol use disorders in an Israeli population sample, investigating trends over time in alcohol, cannabis, nicotine, and hallucinogen use and disorders in US nationally representative population data, and assessing the validity of the DSM-5 substance use disorder criteria and definitions, in general population and clinical datasets. More recently, she collaborated with researchers at Dartmouth University to develop an efficient and reliable online survey to measure cannabis consumption. Currently, Dvora is a Senior Researcher at ICAMH, studying the epidemiology of substance and behavioral addictions in Israeli general population samples, and risk and protective factors for addictions and other mental health disorders, specifically in the context of the Swords of Iron War.
