After graduating, Kiran hopes to learn more about the intersection between her two fields of study through computational linguistics.


Chan Lazaro Hernandez, Admissions Assistant

Chan Lazaro Hernandez is a current student at the City College of New York. He is pursuing his Bachelor of Science in Chemical Engineering. He chose that type of engineering due to the fact that he loves both chemistry and math. As a Dominican-American, he spent most of his life traveling back and forth between the Dominican Republic and New York before finally settling in New York City when he started high school. His passions include science, music, and expanding knowledge in the world. After working with BEAM 6 as a TA/Counselor in summer 2016, he became inspired by the work that the organization does, creating math opportunities for students with social, economic and educational disadvantages. He hopes to continue participating in the opportunities that BEAM give students of his same background.
