Sara Lafia

About

I am a Research Fellow at the University of Michigan's Inter-university Consortium for Political and Social Research (ICPSR) and a Visting Scholar at the University of Chicago's Center for Spatial Data Science (CSDS). My research is currently supported by an NSF project, Transforming Data Discovery Through Behavior Modeling and Recommendation, which is investigating the potential for recommender systems to increase social science data discovery and reuse at ICPSR.

I hold a Ph.D. in Geography from UC Santa Barbara. My interests also include spatial analysis, information visualization, and Semantic Web technologies.
