Hello, my name is Wei-Hao Chen. I am a fourth-year Ph.D. student 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 primarily focuses on technical aspects of Human Computer/AI Interaction (HCI/HAI), particularly in building novel interactive systems that combine Software Engineering and Data Science. I am currently developing tools to help data scientists using several techniques such as LLM, Artificial Intelligence, and Programming-by-Demonstration. I have extensive UI/UX and human-centered design experience in creating tools with AI. Most of my projects are system-centric, aiming to improve the efficiency and usability in a data science pipeline. Previously, I have worked as an Android TV developer in Realtek Semiconductor. My previous research focuses on the theoretical security and privacy of cloud storage systems.
