Dr. Mosi Adesina Ifatunji** is an Assistant Professor in the Department of Sociology and at the Carolina Population Center at the University of North Carolina at Chapel Hill. His research interests are in race, culture, biology and social stratification. To this end, he employs various comparisons between African Americans and black immigrants, not only to document important and increasingly dynamic population trends, but to isolate the role of sociocultural context and practice in the process of racialization and the manufacture of larger trends in social stratification. He uses this quasi-experimental design, which he calls the ‘black ethnic comparative,’ to hold ‘racialized physical features’ (e.g., skin color, hair tenure and bone structure) constant while allowing social, political and historical context to vary in important ways. Ultimately, this design holds unique potential for improving our understanding of how race, culture and biology contribute to social meaning and stratification in society. Dr. Ifatunji also holds a position at the Inter-university Consortium for Social and Political Research (ICPSR) at the Institute for Social Research at the University of Michigan at Ann Arbor where he teaches a course at the Summer Program in Quantitative Methods of Social Research which focuses on Race, Ethnicity and Quantitative Methodologies. The course brings together state-of-the-art theory on race and ethnicity with best practices in the use of social statistics. The course aim is to develop quantitative researchers that will give more careful and keen consideration to how race and ethnicity fit in their statistical models, while also providing race and ethnicity scholars greater ability to understand, critique and use quantitative methods.
