  ## Research
  
  Shahabi’s research is in the area of information management. He is mainly known for his contributions to the field of geospatial information management. Under this area, he has made contributions in several subareas, notably: spatial indexing, geospatial information integration, participatory sensing, geo-social environments, location privacy and ride-sharing. Moreover, he pioneered fundamental concepts such as road-network queries, spatial skyline queries and spatial crowdsourcing. He chaired the founding nomination committee of ACM SIGSPATIAL for its first term (2011-2014 term). He is the chair of the ACM SIGSPATIAL (2017-2020 term).
  
  In addition, Shahabi is responsible (along with Xiaoming Tian and Wugang Zhao) for introducing a new type of tree structure named TSA-tree, based on wavelets. His other work includes the Clustered AGgregation (CAG) algorithm, and the Spatial Skyline Query.
