Professor Johnson’s research interests lie primarily in community-based operations research, and decision models for public-sector facility location and service delivery. Current substantive research areas of interest include: foreclosed housing, subsidized/affordable housing, and urban and regional development. Dr. Johnson also uses cost-benefit analysis to estimate impacts of public policies and information technology to design decision support systems. Prof. Johnson’s research goal is to develop quantitative methods that enable public organizations to serve disadvantaged and vulnerable populations in ways that jointly optimize economic efficiency, beneficial population outcomes, and social equity.
