His research has concerned knot theory, singularity theory, biomathematics, and differential topology. 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
School of Sciences, UNAM is rather different from that of other schools that have their origins in former national schools. The study plan for this faculty was initially given in the Philosophy Faculty of the UNAM. The Biology major was the first one to have a structured study plan, originating around 1930. It was not until 1933 that the majors of Physics and Mathematics were founded. Formerly, the faculty was located in a small building between the Faculty of Engineering and Medicine. Due to the increasing number of students, the Faculty had to construct new buildings, conveniently located among the research science institutes of
