CV
Prof. Ezra completed her Ph.D. at Tel Aviv University under the supervision of Prof. Micha Sharir, one of the world's leading figures in computational geometry. She later pursued postdoctoral fellowships at Duke University, and New York University, and later was an assistant Professor at Georgia Institute of Technology, before joining the faculty at Bar-Ilan University. She is a recipient of the ISF grant for her research on geometric arrangements and algebraic methods in geometry, she is a recipient of the BSF grant for her research on range search, and was previously awarded the NSF CAREER grant for her work on geometric discrepancy . Her work is regularly published in top-tier venues, including SoCG, FOCS, STOC, and SODA.
Research
Computational Geometry and Geometric Algorithms
An autonomous vehicle navigating an urban environment must decipher its surroundings in real time: identifying pedestrians, traffic signs, and obstacles, and calculating a collision-free path. This is the heart of Computational Geometry—the challenge of representing objects in space, calculating distances and overlaps, and making critical decisions in real time.
Prof. Esther Ezra develops the algorithmic infrastructure for solving complex geometric problems. Her research focuses on analyzing spatial structures, partitioning spaces into simpler regions, and providing rapid responses to location and optimization queries within massive datasets.
The central pillar of her work is "The Algebraic Method" - applying the polynomial method in order to decompose complex geometric scenes into units that can be analyzed efficiently. This approach provides advanced methods for geometric incidences, range searching, and nearest neighbor search.
