Personnel: John Jumper at Google DeepMind (Principal Research Scientist; AlphaFold lead)

NoteWhile the source does mention 'John M. Jumper, American chemist and computer scientist,' which could potentially refer to the person in the claim, the disambiguation page provides no substantive information about his employment, roles, organizations, or dates. The source does not confirm or contradict any of the specific claims about Google DeepMind, Principal Research Scientist role, AlphaFold leadership, or the 2017 start date. To verify these claims, a more detailed biographical source would be required.
