Chaya Keller

Chaya Keller (born 1983) is an Israeli mathematician and computer scientist, currently an associate professor in the School of Computer Science at Ariel University. Her research field is discrete and computational geometry.
Biography
Keller was born in Jerusalem to Menachem Mendel and Shulamit Lubin. She studied at the Horev Ulpana High School in Jerusalem, and after completing her national service, she earned her bachelor's degree from Michlala Jerusalem College. She completed her master's and doctoral degrees at the Einstein Institute of Mathematics in the Hebrew University of Jerusalem, under the supervision of Professor Micha Asher Perles. Before joining Ariel University in 2019, Keller was a postdoctoral fellow at the Ben-Gurion University and a research fellow at the Technion.
Keller specializes in discrete and computational geometry, including convexity, coloring problems in geometric graphs and hypergraphs, and geometric graph theory. Among her contributions to the field, together with other researchers, are the solution of Ringel's problem on coloring tangency graphs of circles in the plane, improved algorithms for finding conflict-free colorings of geometric hypergraphs, which has applications to frequency allocation for cellular antennas, and finding effective quantitative bounds for the (p,q) theorem in convexity theory.
Keller is married to the mathematician Professor Nathan Keller and is a mother to eleven children. She resides in Jerusalem.
Awards
Keller won the Baroness Ariane de Rothschild Fellowship for Outstanding Female Doctoral Students (in the first cohort of recipients), the Hoffman Fellowship for Outstanding Doctoral Students, and the Noriko Sakurai Award for an Outstanding Postdoctoral Fellow at the Center for Advanced Studies in Mathematics at Ben-Gurion University. In 2022, she was selected for TheMarker's 40 Under 40 list, and in 2024 she won the Krill Prize awarded by the Wolf Foundation.<ref name":0" /><ref name":1" />
