NoteThe source confirms Heim's RAND affiliation and demonstrates expertise in hardware-enabled governance mechanisms and AI compute topics through his publications. However, the source is a publications page, not a biographical profile. It does not explicitly confirm: (1) his specific title as 'compute governance researcher', (2) affiliations with Epoch AI and GovAI, (3) expertise in 'AI compute supply chains' or 'compute measurement' as stated, or (4) authorship of 'cautious analysis of HEM limitations.' The publications list supports some expertise claims but does not provide the comprehensive biographical description claimed. The claim's 'as of 2026-03' date is consistent with the 2026 publication shown, but the source lacks explicit confirmation of most biographical elements.
