Personnel: Dan Hendrycks at University of California, Berkeley (PhD Student)

NoteThe source confirms all key fields in the record: (1) person name 'Dan Hendrycks' is correct, (2) organization 'University of California, Berkeley' is confirmed, (3) role as PhD Student is confirmed by the Ph.D. degree, (4) endDate 2022 is explicitly confirmed. The startDate of 2018 is not directly stated in the source, but this is consistent with the timeline (B.S. in 2018, Ph.D. in 2022 suggests PhD studies began around 2018).
