The underlying theme of Professor Steffensmeier’s research is understanding how stratification (age, gender, race, class, spatial) and culture impact level of crime and social control efforts. Longstanding and current research and theoretical interests include a particular focus on the age-crime relationship and its variability over time, across cultures, and by population subgroup. A related focus concerns pathways into and out of crime, versatility and specialization in criminal careers, and the effects of social and biological aging on rewards and risks of criminal involvement. Steffensmeier has extensive experience working on research projects that involve data triangulation approaches and applications of both qualitative and quantitative methods. This experience is reflected in a recent monograph (Confessions of a Dying Thief ), an ASR 2013 article, titled: “Gender and 21st Century Corporate Financial Crime,” and a current cross-national project studying the age-crime relationship in Taiwan vis a vis United States.
