The GeoSocial Lab is home to research projects aimed at developing innovative computational and visual tools to better understand and analyze massive and complex geo-social networks. The lab is affiliated with the Department of Geographical and Sustainability Sciences and Iowa Informatics Initiative (UI3)  at the University of Iowa and directed by Caglar Koylu.

On this site, you will find links to research, publications and software focusing on developing new theories and applications for understanding massive geo-social networks. Sharing of research findings from diverse subject areas such as migration, spatial analysis of social networks, idea diffusion, political influence, disease spread and other analysis of social media data will help foster multiple perspective thinking and build a community that is particularly interested in combining theories and methodologies of diverse fields.
