Hey everyone! My name is Brian, and I’m a high school senior from the Bay Area in California. I’m fascinated with the digital side of our world and all the information it holds under the surface. From my statistics and computer science courses, I discovered the field of data science. Before Penn’s summer Data Science program, I would’ve never dreamt of being able to model such complex datasets and draw real-world conclusions from them. I’m a pretty curious person, and if you ever see me outside of the classroom, there’s a good chance I’ll be reading an article online or exploring something new. In my free time, I really enjoy going outdoors for a run, playing soccer, and getting boba with my friends. I love getting some fresh air and enjoying nature!
