Ieke de Vries, Ph.D. - Department of Criminology, The Institute of Criminal Law and Criminology
In her doctoral work, Ieke de Vries utilized unique online and administrative data to identify the spatial and social mechanisms that drive commercial sex and sex trafficking in illicit massage businesses in the U.S. Specifically, she examined the geographic and spatial features of census tracts and cities that have illicit massage businesses, analyzed the mobility of clientele through a spatial network approach, and evaluated the impact of police shutdowns on the overall geographic distribution of illicit massage businesses. Her research was awarded a Research Fellowship from the National Institute of Justice in the U.S. More broadly, her research agenda focuses on human trafficking and exploitation, law enforcement responses to emerging and newly defined crime types, digital opportunities for crime, risk factors for (repeat) victimization, and the broader socio-ecological context of crime. To investigate these themes, she employs quantitative and computational methods, sometimes in addition to qualitative approaches. Examples of these methods are qualitative interviews, digital research methods, regression analyses, social network analyses, spatial analyses, and machine learning.
