Improving my Resume for STEM Schools

I am a high school sophomore dual enrolled in a community college where I am working on my A.S. in Physics, and all college classes that I take also go onto my high school transcript. I will finish high school with ~4.3/4.0 Weighted GPA, and I will have taken about 45 science credits from college.

I am planning on double-majoring in Astrophysics and Quantum Physics, and am currently writing a research paper that will be submitted to a top 100 science journal. I am working with several professors and astrophysicists to guide me, and hope to write a second paper before I graduate.

I am also the Trumpet section leader for my high school's Marching Band, which consistently wins Regional competitions and places top 5 in the state. Additionally, I am part of the highest concert band for my school.

I currently work at a fast-food restaurant and might apply for a NASA internship next fall.

I'm worried that my college resume is not broad enough for the schools I want to go to:

Caltech

MIT

Princeton

CU Boulder

What can I do to broaden my resume? Thank you!
