Gregory Scott Chirikjian (born 1966) is an American roboticist and applied mathematician, primarily working in the field of kinematics, motion planning, computer vision, group theory applications in engineering, and the mechanics of macromolecules.

He is known for his theoretical contributions to the kinematics of hyper-redundant (snake-like and continuum) robots and stochastic methods on Lie groups.

[1] In the same year, he joined the Department of Mechanical Engineering at Johns Hopkins University as an assistant professor.

[2] From 2014 to 2015, he served as a program director for the US National Robotics Initiative, which included responsibilities in the Robust Intelligence cluster in the Information and Intelligent Systems Division of CISE at the National Science Foundation (NSF).

[5] Chirikjian was named NSF's Young Investigator in 1993,[2] Presidential Faculty Fellow in 1994,[2] and was a recipient of the ASME Pi Tau Sigma Gold Medal in 1996.
