Service Access: Measurement and Inference

Service access is the study of a population's access to services that are considered fundamental in fostering economic development, improving wellness and enhancing the general quality of life of a population within a given geographic area. Research in service distribution equity is needed in many areas including estimation of the extent of the existing inequities, measurement of the associated economic and health costs, and identification of potential catalysts to reduce the inequities. My research focuses primarily on developing new statistical methods that account for both time and regional variations along with identifying underlying contributors in the inequity of service distribution. The goal is to build the foundation of measuring and monitoring service distribution inequity, to ultimately improve decision making and fairness. This web page has been initiated with the National Science Foundation support (CAREER Award CMMI-0954283).
