The research topics of this group are centered on n-dimensional data modeling and analysis, from both methodology and application points of view. The team's interdisciplinary skills result in projects that cover a wide range of scientific topics including Geometry, Data Mining, Machine Learning, Data Structures, and their interactions for several fields of application. | The research topics of this group are centered on n-dimensional data modeling and analysis, from both methodology and application points of view.

* **Computational geometry**: We design algorithms and data structures for numerous geometric problems related to range searching, geometric graphs, and several other topics. We analyze that asymptotic complexity of these algorithms and also prove lower bounds for the complexity of the problems. | * **Computational geometry**: We design algorithms and data structures for numerous geometric problems related to range searching, geometric graphs, and several other topics.
