In the final two weeks of June 2026, AI company Anthropic poached four top-tier researchers, escalating the Silicon Valley talent war into academia. On July 1, Jelani Nelson, chair of the Computer Science division in the Department of Electrical Engineering and Computer Sciences at UC Berkeley, announced he had joined Anthropic as a Member of Technical Staff and would take a leave of absence. Less than two weeks prior, on June 19, 2024 Nobel laureate in chemistry and AlphaFold core developer John Jumper left DeepMind to join Anthropic. According to a Bloomberg report on June 24, Jumper's two core collaborators, Jonas Adler and Alexander Pritzel, also followed him from DeepMind; both were key contributors to Gemini model pre-training and coding capabilities. Nelson's move signals that the competitive focus is shifting from engineering implementation to deeper theoretical levels. Nelson, who earned his Ph.D. in computer science from MIT in 2011, focuses on streaming algorithms and dimensionality reduction.
