Assistant ProfessorCriminal Justice


I began my graduate career at Sam Houston State University, where I focused my educational pursuits on research methods, advanced statistical procedures, and psychometrics. I learned valuable skills during this time, such as survey development, structural equation modeling, and multi-level modeling. Also during this time, I also developed a research agenda focused on risk assessment, primarily among individuals who have sexually offended and justice-involved women. More specifically, I am interested in the development and assessment of gender-responsive risk assessments, with the goal of improving criminal justice responses to this population. Additionally, I am in the process of developing a comprehensive problematic pornography use instrument, with the goal of improving decision-making among criminal justice professionals tasked with treating and supervising individuals who have sexually offended. After graduation, I accepted an Assistant Professor position in the Department of Criminal Justice and Social Work at the University of Houston-Downtown. It is my intention to continue this line educational and research pursuits while serving in this role at this fantastic university!
