Ofer Biham (Hebrew: עופר ביהם) is a faculty member at The Racah Institute of Physics of the Hebrew University of Jerusalem in Israel. Biham received his Ph.D. for research on quasiperiodic systems at the Weizmann Institute of Science in 1998, under the supervision of David Mukamel.
In later years, Biham was involved in the development of methods for the calculation of unstable periodic orbits in chaotic systems, models for efficient simulations of traffic flow and quantum computation.
The focus of Biham's current research is on the development of computational methodologies for the simulation of in interstellar chemistry and in genetic networks. Biham is known for the Biham–Middleton–Levine traffic model, which is possibly the simplest model containing phase transitions and self-organization.
