Otto Bahnhoff

Otto Bahnoff (John Cariani), who prefers to be called "Ottobahn" like Autobahn, is a brilliant but nervous and excitable CalSci engineer. Otto specializes in plasma physics and technology.

Background
Very little is known about Bahnoff's background and family. Although he attended a college or university where he gained at least one Ph.D before he was employed at the California Institute of Science (CalSci).

Personality
Otto is a brilliant engineer specializing in plasma physics and technology, but he easily gets nervous and is very excitable. He speaks very fast, is constantly in motion, and is able to come to a conclusion just by glancing at a spec sheet he has never seen before along with some of Charlie's equations.

Numb3rs Season 6
Otto appears in three episodes in season six: Dreamland, Arm in Arms, and the show's finale, Cause and Effect.

He serves as a foil for Charlie with his apparent genius, ability to get completely lost in his work, and early uneasiness with criminal violence. As Larry takes over Charlie's FBI responsibilities for his leave to Cambridge, the enthusiastic Otto serves as assistant to Dr. Fleinhardt. He triumphed with physicists replacing the mathematicians.
