Arnold Filtser is a postdoctoral research scientist at Columbia University at the Department of Computer Science. Arnold obtained his Ph.D. in computer science from Ben-Gurion University of the Negev (BGU), under the dual supervision of Robert Krauthgamer (Weizmann) and Ofer Neiman (BGU). His thesis title is “On Refined notions of Embeddings.’’
Arnold’s research interest is in theoretical computer science, focusing on the analysis of algorithms. More specifically: metric spaces, low-distortion embeddings, high-dimensional geometry, spanners, stochastic decompositions, approximation, data summarization and sub-linear algorithms.
