Fields Medal Winner Jacob Tsimerman Quits Math, Joins OpenAI Before Summer's End
Newly minted Fields Medal winner Jacob Tsimerman is leaving academic mathematics for artificial intelligence. He has announced he will stop accepting PhD students and will formally join OpenAI before the end of this summer. According to National Business Daily (每日经济新闻), his goal is to find ways to control AI and head off what he calls a potential "civilization-level extinction risk." Tsimerman's move comes as safety teams at major AI companies accelerate the recruitment of top scholars from fields well beyond computer science. Anthropic has hired a Stanford University economist and a philosopher from the University of Texas at Austin. OpenAI, for its part, has brought in a roster of leading mathematicians and physicists. The report also points to 2026 figures: at least 22 professors have left, or temporarily stepped away from, elite institutions including Stanford, Berkeley, Harvard and MIT. They now work at OpenAI, Anthropic, Meta or Google DeepMind, according to the same report.
