"In honor of Fil-Am History Month this October, I am starting this project to feature Filipinx inventors and innovators throughout the course of history. By recognizing their contributions to the advancements in the different fields of STEM, my goal is to reinforce this idea that people of color have had significant contributions in a field where they are often underrepresented, and will continue to be a driving force of scientific progress. These Filipinx individuals have had done these important contributions in the past, and YOU could also be one of them in the future!" - Wesley Sosa, Corresponding Secretary/STEM Chair
