Zixin Guo

I'm a fourth-year PhD student at Department of Computer Science, Aalto University. My current research interests include:

Multimodal Learning, advised by Jorma Laaksonen (Aalto University, Finland 🇫🇮) and in collaboration with Min Cao (Soochow University, China 🇨🇳).
Eye Tracking, in close collaboration with Yue Jiang (University of Utah, USA 🇺🇸).
