What we found

Supports. Wikipedia (2018) states that Sheinbaum completed the work for her Ph.D. thesis between 1991 and 1994 at Lawrence Berkeley National Laboratory in California, and that she analyzed energy use in the Mexican transportation sector there.[2]

Supports. Al Jazeera (2026-07-11) says Sheinbaum conducted her doctoral research at Lawrence Berkeley National Laboratory while earning her doctorate from UNAM, consistent with the claimed thesis work at the laboratory.[3]

Supports. Reuters (2024) reports that while preparing her doctoral thesis she spent time at the University of California at Berkeley, and that she earned her doctorate in 1995, which is consistent with the claimed 1991–1994 period at the laboratory.[1]

Context. Several other sources (Heart the Boat Sing, AA, Populartimelines, Hoymx, Alteryx, Wikiwand German) repeat the same 1991–1994 Lawrence Berkeley wording, likely traced back to Wikipedia, so they add little independent corroboration.[4][5][6][7][8][9]
