Leonidas John Guibas (Greek: Λεωνίδας Γκίμπας) is the Paul Pigott Professor of Computer Science and Electrical Engineering at Stanford University, where he heads the geometric computation group and is a member of the computer graphics and artificial intelligence laboratories.

Education and career[edit]

Guibas was a student of Donald Knuth at Stanford, where he received his Ph.D. in 1976.[1] He has worked for several industrial research laboratories, and joined the Stanford faculty in 1984. He was program chair for the ACM Symposium on Computational Geometry in 1996.[2]


The research contributions Guibas is known for include finger trees, red-black trees, fractional cascading, the Guibas–Stolfi algorithm for Delaunay triangulation, an optimal data structure for point location, the quad-edge data structure for representing planar subdivisions, Metropolis light transport, and kinetic data structures for keeping track of objects in motion.

He has Erdős number 2 due to his collaborations with Boris Aronov, Andrew Odlyzko, János Pach, Richard M. Pollack, Endre Szemerédi, and Frances Yao.[3]

Awards and honors[edit]

Guibas is a Fellow of the ACM[4] and the IEEE,[5] and was awarded the ACM - AAAI Allen Newell Award for 2007 "for his pioneering contributions in applying algorithms to a wide range of computer science disciplines."[6] In 2017 he was elected to the National Academy of Engineering.[7] In 2018 he was elected to the American Academy of Arts and Sciences.[8]
