Pedro joined the mathematics department in the College of Arts and Sciences in 1967.  He brought with him a wealth of experience outside of the academic world, having work in applied mathematics at NASA and BF Goodrich. At Grand Valley, Pedro became a dedicated educator and turned his interests to theoretical mathematics, delving into Fractal geometry and Chaos. He gave several departmental seminars on this topic in the 1980s (one was a joint talk with two students and an automotive professional from General Motors).  Pedro was also among the faculty who worked to introduce the use of graphing calculators in the teaching of mathematics. In addition, in the 1990s he was involved in the design of a new capstone course, as well as a redesign of the mathematics major.

Outside of the department, Pedro taught the class "Teaching Elementary Math Bilingually" for the Graduate School of Education. This course had two goals: to teach math skills to those who wish to teach at the elementary level, and to give students some competence in technical Spanish to help them in teaching their students whose English may be a second language. In his other life, Pedro enjoys chess, bridge, and go.
