research overview

Dr. Howe's research interests include better characterizing, adapting, and applying advanced quantitative methods to enhance causal inference based on data from experimental and observational studies. Specifically, her work has focused on using advanced causal inference techniques to address selection bias, to address confounding bias, and to perform mediation analyses when the aim is to identify the best targets for effective interventions to improve population health as well as to reduce persistent health disparities. Such disparities include inequalities in HIV disease and cardiovascular health by race/ethnicity as well as socioeconomic and neigbhood-level factors.
