Build AI-powered tools for data scientists, developers, and end-users

Hello, my name is Wei-Hao Chen. I am a Ph.D. candidate in the Department of Computer Science at Purdue University and a member of the Human-Centered Software Systems Lab under the guidance of Professor Tianyi Zhang.

My research focuses on Human-Computer/AI Interaction (HCI/HAI), building novel interactive systems for data scientists, developers, and end-users using LLM, AI, and Programming-by-Demonstration. Most of my projects are system-centric, aiming to improve efficiency and usability within data science pipelines.
