Greetings! I'm Zhengtai, an undergraduate HCI researcher from Tsinghua University, currently visiting professor Yalong Yang's group in Gatech. My research interests focus on XR, health/accessibility, and immersive analytics. I’m passionate about building adaptive, context-aware and semantic-aware immersive interfaces through understanding of user perception, intents, and affective states, empowered by AI and pervasive sensing.
I envision a future where immersive experiences are tailor-made for all.
For fall 2025, I'm actively seeking Ph.D. positions. Please have a look at my research works if you want to recruit a self-motivated Ph.D. candidate!
