I'm Harrison He. Although my academic path points toward Mathematics and Computer Science at the University of Illinois Urbana-Champaign, my identity extends far beyond the classroom. As an INTJ, I naturally approach challenges with analytical thinking and objective logic, yet I am equally driven by a deep curiosity to experience life from multiple perspectives.
I thrive on staying active and exploring new environments—whether I'm scaling a climbing wall, hiking a scenic trail, playing badminton, or unraveling puzzles in an escape room. When it's time to decompress, you will often find me listening to music, brewing traditional Chinese tea, getting lost in web novels, or jumping into a match of League of Legends.
