Junjie (Jorji) Chen
My Chinese name is 陈俊杰 // 陳俊傑 [Sounds like: Ch-urn June-Jee-eh].
You can call me Jorji.
I was born in November 2002 in Lu’an, Anhui, China. I am a PhD student at Hefei University of Technology (HFUT), advised by Prof. Meng Wang (汪萌). I am also fortunate to have been guided by Prof. Yanbin Hao (郝艳宾) and to have collaborated with Prof. Linfeng Zhang (张林峰).
💡 I am broadly interested in understanding how AI systems can better model human psychological and emotional states, and how such understanding can be incorporated into practical and efficient interactive systems.
🎯 Research Focus
I am primarily interested in the following research question:
How can we build psychologically grounded, fine-grained, multimodal, efficient, evolving, and full-duplex conversational AI systems that better understand and respond to human emotions?
In particular, I am learning and exploring:
- 🧠 Psychology-informed modeling of emotion and cognition in dialogue systems.
- 🎭 Fine-grained emotion perception, including subtle, dynamic, and context-dependent affect.
- 🔊🖼️ Multimodal interaction, combining language with visual, acoustic, and behavioral cues.
- ⚡ Efficiency-aware methods for building deployable and scalable dialogue models.
For a deeper dive into my current directions and methodology, read Research Interests.
