* **Clustering methods**: We study fuzzy clustering algorithms, or semi-supervised clustering, also referred to as constrained clustering. Such methods use background knowledge in order to improve the accuracy of the solution. | * **Clustering methods**: We study fuzzy clustering algorithms, or semi-supervised clustering, also referred to as constrained clustering.

* **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.
