Zachary M.

Zachary M. is presently in his last year of his study for his dual masters in math and physics at UTSA. Some may say that in doing so, he is trying to prolong his adolescence and avoid adulthood. But truth be told, Zach is very passionate about his studies. This was not always the case. Admittedly, Zach was mathematically challenged in middle school (his mom would help him with his algebra homework). But something clicked for him in high school. He took every AP math and science class that he could and went so far as to participate in academic UIL. After graduation from high school, Zach began studying math and physics at UTSA. He took up a job as a physics tutor on a whim but came to discover that he really enjoys helping people learn. Now as a graduate student, Zach teaches introductory physics labs. In doing so, he does his best to accommodate all of his students while simultaneously emphasizing the mathematical and theoretical underpinnings of physics.
