I am a PhD student in Computer Science at UChicago, advised by Chenhao Tan.

My Current Focus and Passion

Human-AI Decision Making (especially in medical domains)
Radiology Reports Generation
AI Diagnostic Tools (for Prostate Cancer Analysis)
AI Teaching in Medical Settings

I am passionate about putting humans at the center of AI development, including how to understand the process of human-AI interaction (often neglected from a cognitive and psychological perspective along with a technical lens), and how we can better build/deploy AI tools that can actually be useful in real-world settings, especially in medical contexts.
