I have 30 years of experience, and specialize in the field of sociology with specific knowledge in the areas of criminology, demography and statistics. I have published on such topics as geography and ecology of crime, demography and population and statistics and research methodology. I have testified 15 times on topics such as third party crime premises liability, discrimination and redistricting and voting rights. I am an applied sociologist, demographer and criminologist with extensive training and expertise in statistical and social science research methods. While I have expertise in several social science areas, I have also been hired in matters that are primarily statistical in nature.
