Greetchen Díaz Muñoz is a Puerto Rican scientist and the current Director of the Science Education Program at Ciencia Puerto Rico. She was named an AAAS IF/THEN Ambassador in 2019.

Early life and education 
Díaz was born and grew up in Ponce, Puerto Rico, the oldest of five siblings. She grew up in a violent neighborhood and, although her family had limited resources, her teachers remarked her curiosity and aptitude. Attending the Residential Center of Educative Opportunities of Mayagüez (CROEM), a magnet high school specializing in math and science, from which she graduated in 1997, would change her life. In 2002, she graduated magna cum laude with a bachelor's of science in biology from the University of Puerto Rico, Mayagüez. She received her master's degree in biology at the University of Puerto Rico, Mayagüez in 2006, and her Ph.D. in 2012 from The Ohio State University. She next completed a post-doctoral fellowship position in virology at the University of Nebraska-Lincoln working on HPV.

Career 
A landmark development in Díaz's career in science advocacy was the November 2013 launch of the "Boriqueña" blog, hosted by CenciaPR. The purpose of the blog is "to focus attention on the scientific contributions of Boricuas and Hispanic women and thereby motivate and set an example for future generations of female scientists." In 2014, Díaz started working at the Puerto Rico Science, Technology and Research Trust, overseeing the organization's grants program. She joined Ciencia PR in 2017 as Director of the Science Education Program, where she fosters the participation of STEM experts in K-12 education, focusing specifically on providing opportunities for Latina girls and young women.
