Another element that influenced his first studies as archaeologist, was that during his childhood he spent many days exploring the old ruins of Teotihuacan, years before its reconstruction.
He returned to study at the National School of Anthropology, where he completed his master dissertation "Excavations at the archaeologic zone of Cerro del Tepalcate" (1961).
From 1955 to 1959 was assistant of Alfonso Caso during excavation and register works in archaeological sites in Quiotepec, Tecomavaca, Los Cues, and Cuicatlán, Oaxaca.
In 1972 he conducted consolidation works at Tulum ruins, and in 1973 he developed the project for the Archaeological Museum of Tlapacoya, Estado de México.
His most important contributions to Mexican archaeology were the recovering of the ruins of Santa Cecilia Acatitlan and the studies about the yacatas structures in the Michoacán area of Tzintzuntzan.
