Incoming freshman Christopher Suplice has Leber’s hereditary optic neuropathy, a condition that has left him mostly blind. His experience has motivated him to use computer science to create technology for people with visual impairments, like himself.

Frinny Polanco Walters, MD, is an attending physician in the division of adolescent and young adult medicine at Boston Children’s Hospital, a fellow in the Commonwealth Fund Fellowship in minority health policy at Harvard University, and an MPH candidate at the Harvard T.H. Chan School of Public Health. Dr. Walters is an Afro-Latinx doctor who was born in the Dominican Republic and grew up in Jamaica Plain, a suburb just outside Boston. She attended college at Brown University and moved to Washington, D.C., thereafter to serve as a Congressional Hispanic Caucus Institute Fellow, working alongside health policy experts to address issues affecting underserved communities. While in the D.C. area, Dr. Walters also worked at the National Institutes of Health researching the lack of involvement of minority populations in clinical trials. Next, she started her medical career at New York Medical College and returned to Boston for a pediatrics residency at the Floating Hospital for Children at Tufts Medical Center and a fellowship in adolescent medicine at Boston Children’s Hospital.


Since Gabrielle Rigaud’s days in the Bridge to Calculus program back in 2000, she’s enjoyed a career in the field of civil engineering, specifically as a geotechnical engineer. After Ms. Rigaud immigrated from Haiti and struggled to learn English, Bridge to Calculus prepared her to take AP Calculus, pass the AP exam, and eventually attend college at Tufts, with the advantage of having AP course credit and a strong foundation in math. The knowledge and confidence Ms. Rigaud gained from the program made engineering an obvious choice despite the rigorous and challenging coursework. She went on to pursue a master’s degree, which has helped her support emergency disaster efforts in the U.S. and around the world, and built the base for a fulfilling career in an exciting STEM field. Two decades later, Ms. Rigaud is forever grateful to her high school teacher, Dr. Krishna Rajangam, for signing her up for the Bridge to Calculus program, and for her mentor and friend, Professor Robert Case, for feeding her curiosity and making calculus seem easy during her summer in the program.


The John D. O’Bryant School of Mathematics and Science’s program and teachers prepared Yuyu Chen for AP calculus, opened life-changing doors for him, and equipped him with the resources to succeed as a mathematics major in college. The program also inspired him to pay it forward by becoming a teacher after graduation. Mr. Chen also returned to the Bridge to Calculus program to serve as a teacher and mentor at his former high school—an experience he called “amazing!


As a Boston Public Schools alum and the salutatorian of her graduating class, Daniela Alarcon-Diaz was awarded Northeastern’s Boston Public High School Scholarship and is currently pursuing a bachelor’s degree in business administration at the D’Amore-McKim School of Business. Ms. Alarcon Diaz is a proud Latina and Bridge to Calculus alum excited to have the opportunity to work in the Question Center and to provide mentorship to Boston Public School students through the Bridge to Calculus program. Ms. Alarcon-Diaz is also grateful to be part of the BtC Committee and advocate for the program and the needs of the students


Tristan Campbell is a BtC program 2008 alumnus. He describes the program as a true bridge, ‘paving the way for him to hit the ground running’ at Boston University, where he studied electrical engineering with a focus on computer engineering and science. Since that time, Tristan has been involved in multiple projects, including Android application development, embedded radar, attached storage file systems, and cloud computing.
