Weiyan Shi

Welcome! I am a fifth-year PhD student in Computer Science at Columbia University, advised by Prof. Zhou Yu, working on Natural Language Processing. Previously, I completed my master’s degree in Statistics from the University of California, Berkeley and my B.S. in Mathematics from Renmin University of China. I have worked in the SF bay area as a full-time data scientist on customer service chatbots for two years before starting my PhD.

This past fall I was co-teaching Conversational AI (COMS 6998) with Zhou at Columbia.

I am on the faculty job market looking for tenure-track positions :)

Research Overview

My research interests are in Natural Language Processing, especially intelligent interactive systems 🤖 and the following directions:

My research vision is to build a natural interface between human intelligence and machine intelligence via natural conversations, so that all members of society can interact with AI models seamlessly regardless of their backgrounds. Glad we are going in that direction with ChatGPT!
