López de Medrano did his undergraduate studies at UNAM, and earned his Ph.D. from Princeton University in 1969, under the supervision of William Browder. He returned to UNAM as a researcher and professor in 1968, and was president of the Mexican Mathematical Society from 1969 to 1973. López de Medrano presented his work on knot
Unam sanctam matters in France — at Rome. Philip forbade Saisset or any of them to attend and forestalled Boniface by organizing a counter-assembly of his own, held in Paris in April 1302.
