Charles Grigsby-Calage, Ph.D

Postdoctoral Researcher

''I am a post-doctoral researcher and lecturer in the University of Florida’s Food and Resource Economics Department. I have research expertise in food systems, food retail markets, food insecurity, socioeconomic inequality, and community economic development. I am interested in combining frameworks from economic theory with novel data, machine learning, and causal inference techniques to address complex research questions in the context of changing food systems. Additionally, I have diverse teaching and outreach experience working with communities, entrepreneurs, and farmers in the United States and internationally. 

My dissertation investigated the economic impacts and implications of the expansion of dollar stores across the United States. I employed machine learning (ML) models to study dollar store growth from 2000 to 2020, leveraging their data-driven approach and predictive accuracy to understand dollar store location strategies. I also used an ML imputation method to investigate the causal effects of dollar store entry on household food access and on competition with small grocery stores and supermarkets. 

Before pursuing my doctoral studies at the University of Florida, I studied economics at the University of the South: Sewanee and earned a master's degree in agricultural and resource economics at the University of Tennessee, Knoxville. Between academic degrees, I served in the US Peace Corps Costa Rica's Community Economic Development (CED) program and worked as an extension marketing specialist focusing on value-added agriculture and direct marketing with the University of Tennessee's Center for Profitable Agriculture.
