He served as a federal deputy in the last Porfirian legislature (1908–1910), where he befriended Venustiano Carranza.

He was imprisoned in Lecumberri when that legislature was dissolved by Victoriano Huerta.

He joined the constitutionalist movement, becoming the first Rector of the National University (Universidad Nacional Autónoma de México; UNAM). In Veracruz, Venustiano Carranza, the "First Constitutional Chief," entrusted him with drafting the Reform to the Mexican Constitution, which served as the basis for the Constitutional Congress of Querétaro to draft the Political Constitution of 1917.

He headed the University and Fine Arts department. He supported the creation of the National School of Industrial Chemistry, a precursor to the Faculty of Chemistry of the National Autonomous University of Mexico, inaugurating its facilities in September 1916. In 1917, he assumed the Rectorship of the National University again, with his tenure marked by the establishment of research laboratories.

In 1920, he accompanied President Carranza in his flight towards Veracruz, parting ways with him in the community of Aljibes, where the Carrancista convoy was attacked by Obregonista forces. He was taken prisoner and incarcerated again in Lecumberri. After months of captivity, he was released on the condition that he left the country. He traveled through Europe, and later settled in San Antonio, Texas, before eventually being able to return to the country.
