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

NoteThe source is a disambiguation page that does not identify which 'John Jumper' is the subject of the claim, nor does it provide any information about employment at Google DeepMind, the role of Principal Research Scientist, AlphaFold leadership, or a 2017 start date. The source mentions 'John M. Jumper' as a Nobel Prize-winning chemist and computer scientist, which could potentially refer to the same person, but the disambiguation page provides no details about his current or past employment. To verify the record's claims about Google DeepMind, role, and start date, a source with substantive biographical information about the specific John Jumper would be required.
