Symbolic Systems

Stanford University

Hi there! I’m Charles (he/him/his), a junior majoring in Symbolic Systems. I’m interested in all things climate, and I’m excited about interdisciplinary approaches to understand and solve environment-related problems. At Stanford, I’ve worked on projects such as developing extreme heat/air pollution sensors for low-income seniors, researching materials for organic solar cells, and building AI tools for clean energy developers. In my research, I look forward to studying evolving environmental attitudes online within an ever-changing world. In my spare time, I love watching & making movies, playing ultimate frisbee, and spending time outdoors.
