Errol L. Montes-Pizarro is a professor of mathematics at the Institute of Interdisciplinary Research at the University of Puerto Rico, Cayey Campus. He received his Ph.D. in mathematics from Cornell University. In addition to his research in mathematics, he also studies the history of Afro-descendant music with an emphasis on the continuous exchanges between Africa and Afro-American cultures. He recently published Más ramas que raíces: Diálogos musicales entre el Caribe y el continente africano (Ediciones Callejón, San Juan, 2018).  In this book, Montes-Pizarro analyzes the dialogues between Afro-Caribbean music and several musical genres in the African continent from the 19^th century to the present as well as recent influences of African popular music on the Caribbean. Since 2001, Montes-Pizarro has produced and hosted the radio program Rumba Africana for Radio Universidad de Puerto Rico and aired in Barranquilla, Colombia. During his 2018 summer visiting fellowship at PLAS, Montes-Pizarro will work on a research project that aims to document and analyze the African influences on Caribbean traditions of string instruments (chordophones). Montes-Pizarro will be at PLAS from July 22 to August 4, 2018.
