Hello! My name is Katharine Moon Vari.

I am a student at Columbia University, an engineer, and interested in promoting tech development in the arts and media. 

At Columbia, I am in the Fu Foundation School of Engineering and Applied Sciences. I am majoring in Computer Science and doing a minor in Art History. In Spring 2026, I will be studying abroad at Cambridge University’s Pembroke College, studying Classics and Computer Science.

I’ve done some research at UCSC in machine learning and at Columbia in VR, and I worked at Warner Bros. Discovery last summer doing software engineering. 

You can find me in San Francisco or New York, or just email me!
