Overview
Catherine's expertise is in the design and implementation of epidemiological studies among marginalized populations with a focus on qualitative and quantitative methods. Her research aims to identify the social and structural causes and consequences of disparities in substance use harms (including overdose), mental health, and access to healthcare in marginalized populations such as people who use drugs and/or sell sex. Catherine's recent research includes: examining overlapping structural vulnerabilities among women sex workers in Baltimore and their effects on long-term mental distress; evaluating implementation of state-funded programming aimed at reducing fatal overdoses in Maryland; evaluating the racial equity and public health impacts of drug decriminalization policy in Baltimore; implementing COVID-19 testing for women who use drugs in partnership with a community-based organization in Baltimore. She is experienced in latent variable analysis, structural modeling, and psychometrics, particularly in research with mental health constructs, internalized stigma, and substance use.
