lethal violence
My first line of research focuses on urban violence, with specific attention to macrostructural forces that contribute to variation in rates of homicide and violence across time and space. With substantial fluctuations in crime rates over the past few decades, much of my focus thus far has been on temporal trends in overall and disaggregated homicide rates.

crime clearance
A second line of research focuses on police response to violent crimes, particularly in the form of clearance (i.e., arrest) for crimes. With currently less than two-thirds of homicides cleared by arrest (and much less for other crime types), and serious implications of low clearance rates for families and loved ones, communities, law enforcement, and the potential for criminal deterrence, this is an important, yet understudied, area of research and much of my work has focused on this topic. While I am engaged in multiple papers related to this topic, I aim to contribute a macro-approach to this body of research, as well.
