Clayton Cohn

PhD Student, Research Assistant at Vanderbilt University

About Me

Greetings! My name is Clayton Cohn, and I am a computer science PhD student and research assistant at Vanderbilt University. My concentration is Artificial Intelligence (AI) with a focus on Natural Language Processing (NLP) in learning environments.

I like to stay active, so I play hockey and golf and also lift weights. I'm a committed Francophile and belong to two French meet-ups that help me improve my language skills and gain additional exposure to French culture. I also enjoy volunteering and participate in two charitable organizations through Vanderbilt. I like taking advantage of Nashville's live music scene, and I enjoy playing guitar.

More than anything, I like to challenge myself. I like to solve problems and learn new things. I like to engage in constructive discourse and hear opposing points of view. I like to broaden my horizons and expose myself to activities outside of my comfort zone.
