Mathematics
Foundations through calculus, discrete math, linear algebra, and differential equations.
Writing & philosophy
Essays, argumentation, close reading, ethics, research, and turning ideas into clear prose.

In developmentAbout David
Curiosity is more useful when you can share it.
I’m a Grandview, Texas graduate and Harvard College student studying computer science and philosophy. My interests move between technical systems and human questions: coding, ethics, argument, combat sports, storytelling, and building useful things.
Teaching is where those interests meet. I care about making difficult ideas understandable without making them shallow—and helping students become capable enough to keep going without me.
