About

Portrait of Shreyan Chaubey

I'm a Data Science graduate of IIT Madras and a former AI research intern at Bud Ecosystem. I like to think about how systems model reality. Specifically, how certain systems represent and process information. Outside of that I like to play video games, listen to music and enjoy cooking.

My research interests are Mechanistic Interpretability, Deep Generative Models, and Theoretical Computer Science. I'm also drawn to digital physics, the idea that everything is fundamentally computational, and to the philosophy of mathematics...
