SAESS is a working research group in Johns Hopkins University Bloomberg School of Public Health, hosted jointly by Department of Biostatistics and the Department of Epidemiology via the Spatial Science for Public Health Center. We are an interdisciplinary group comprising of faculty, post doctoral fellows and graduate students from several departments. We have regular meetings featuring presentations and discussions related to small area estimation, spatial and spatio-temporal statistics.
