Piermaria Jorge Oddone (born March 26, 1944, in Arequipa, Peru[1]) is a Peruvian-American particle physicist.

In 1987, he proposed the idea of using an Asymmetric B-factory to study the violation of CP symmetry in the decay of B-mesons.

In the late seventies and early eighties, Oddone was a member of the team that developed the first Time Projection Chamber (TPC).

He was appointed director of Fermi National Accelerator Laboratory (Fermilab) and took up office on 1 July 2005.

[2][3] Oddone received the 2005 Panofsky Prize in Experimental Particle Physics for the invention of the Asymmetric B-Factory to carry out precision measurements of CP violation in B-meson decays.
