Weapons lab head

摘要

Penrose 'Parney' Albright (pictured) is stepping down as director of the Lawrence Livermore National Laboratory in California (LLNL). The physicist, who has led the laboratory since December 2011, announced his resignation on 24 October, saying that he will continue to pursue his interests in US national security. Bret Knapp, who directs weapons programmes at Los Alamos National Laboratory in New Mexico, will take over on 1 November as interim LLNL director until Albright's successor is appointed.
