The claim that Sheinbaum earned her doctorate at UC Berkeley is contradicted by the tier-1 Reuters profile and by Britannica and Wikipedia, which all place her doctorate at UNAM, with only her doctoral research done at the Lawrence Berkeley National Laboratory.

What was said

… But the point is, these are two, you know, jet setters, at least Scheinbaum, with his communist background. Scheinbaum was in California or Columbia most of the time in the 90s. She's in her sixties now, I think, and she get her, I think she got her doctorate at Berkeley. She finished it, then she got a job at the Intergovernmental Panel on Climate Change at the UN, and when you see these color revolutionary types, even though this wasn't really a color revolution, they go from elitist job to elitist job without a problem …

What we found

Contradicts. Reuters (tier 1) states Sheinbaum earned her doctorate in energy engineering from the National Autonomous University of Mexico in 1995, and only spent time at UC Berkeley while preparing her thesis.[1]

Contradicts. Britannica and Wikipedia both name UNAM as the granting institution for her doctorate, with the doctoral research conducted at Lawrence Berkeley National Laboratory in Berkeley, California.[2][3]

Contradicts. A 2026 post by Sergio Sarmiento directly disputes the Berkeley claim, saying she did not study at Berkeley, sat in on some classes at the Lawrence Berkeley lab, and that her doctorate is from UNAM.[4]

Context. Several weaker outlets (Al Jazeera, Indian Express, Mexico News Daily, CNN) describe Berkeley work or a Berkeley master's degree, and some say she did her doctoral research at Berkeley, but none reliably states a UC Berkeley doctorate.[5][6][7][8]
