Biography:

In Sofia's time at Stony Brook, they plan on studying the intersection of coding and machine learning in relation to galaxies, dark matter, and gravitational lensing. In Sofia's free time, they like to do pottery, write creatively, listen to music and watch shows.  Before becoming a Simons STEM Scholar, Sofia participated in citizen sleuth science for Zooniverse regarding emersion lines and the redshifts and blueshifts of various galaxies. Sofia was also a member of the NYAS "1000 Girls, 1000 Futures" where young girls in highschool are paired with women mentors to build skills in leadership, communication, and science through discussions and collaborative projects.

Leading the Future:

"I envision myself leading the future of STEM by taking an interdisciplinary approach to science—branching out through creative outlets, diverse perspectives, and personal connections. The true impact of research isn’t measured by awards, but by how connected and authentic you feel to the work you’re doing and the change it creates. I want to use everything I learn—from people, my research, and my passions—to drive meaningful, inclusive innovation in STEM."

Why did you become a Simons STEM Scholar?:

"I chose to be a Simons STEM Scholar because I wanted to be a part of a supportive community that both values diversity and representation in STEM. As a Dominican woman pursuing astronomy, I knew how important it was to find a space where I could thrive and be challenged. With the programs full academic support and emphasis on research, it made it a perfect match for my goals and my identity."

What would you say to someone who is applying?:

"If you’re thinking about applying to the Simons STEM Scholars program, do it—especially if you’re passionate about science and want to grow in a space that truly supports you. It’s more than just a scholarship, it’s a community that uplifts students and gives you the tools, mentorship, and opportunities to thrive not only in STEM, but in every aspect of your life."
