John Jumper is a research scientist who led the AlphaFold 2 team at Google DeepMind and shared the 2024 Nobel Prize in Chemistry with Demis Hassabis (Google DeepMind, for AlphaFold) and David Baker (University of Washington, for protein design). On June 19, 2026 he announced he would leave Google DeepMind after nearly nine years to join Anthropic (Source: cnbc.com).
Role: Joining Anthropic (announced June 19, 2026); previously research scientist, Google DeepMind Honors: Nobel Prize in Chemistry (2024), shared with Demis Hassabis (Google DeepMind, AlphaFold) and David Baker (UW, protein design)
Background and roles
Jumper holds a PhD in quantitative chemistry and went on to lead structural-biology work at Google DeepMind. He led the AlphaFold 2 team that produced the model's CASP14 result in December 2020 — a median GDT-TS of 92.4, within experimental error of crystallography for most targets — a result widely treated as the solution to the 50-year-old protein-folding problem.

Honors
The 2024 Nobel Prize in Chemistry was shared between Jumper and Hassabis, for AlphaFold, and David Baker, for protein design. The Nobel committee cited AlphaFold's enabling role in applications ranging from antibiotic-resistance research to plastic-decomposing enzyme design. (Source: AlphaFold (DeepMind))
Jumper is described as the first AI Nobel co-laureate. His progression from a quantitative chemistry PhD to DeepMind structural-biology lead to Nobel laureate occurred within five years of CASP14, a sequence cited in AI-for-science policy discourse as evidence that AI is producing Nobel-recognized scientific contributions.
In June 2026 Jumper's move to Anthropic was reported days after Gemini co-lead Noam Shazeer left Google DeepMind for OpenAI, in what coverage framed as an intensifying talent war among frontier labs as Anthropic and OpenAI approached public listings (Source: cnbc.com).
