Gregory Adler

 was a brilliant robotics scientist from General Atomics International, who was contracted by the United States government to work on the Robobrain project at RB-2851. She was expected to work alongside Anna Karim, his long-time rival, with the expectation that the rivalry would reduce in increased creativity due to competition. Both he and Karim worked off-site, but their research teams assigned to RB-2851 more than made up for their absence, especially once test-subjects started arriving on the scene. Notably, Adler was very sensitive about unnanouced changes to the staff, particularly the addition of Kara Asante to the project.
