Li LIU (刘李)
I am an assistant professor at The Hong Kong University of Science and Technology (Guangzhou) in the AI Thrust. I am also an Affiliated Assistant Professor of the department of Computer Science & Engineering at The Hong Kong University of Science and Technology, Hong Kong. Previously, I graduated from Université Grenoble Alpes, Grenoble, France with a PhD, and I was a postdoc researcher at Toronto Metropolitan University, Toronto, Canada.
I worked on "AI for Social Good", and my research directions are multi-modal audio-visual speech processing, AI robustness and AI for healthcare.

Selected Publications
Topic 1. I began to conduct research on the automatic recognition of French/English Cued Speech (CS) during the PhD and Postdoc periods. I proposed the first Mandarin Chinese CS System, which gains good feedback from international reviewers and CS society. By successfully introducing the deep neural network models into CS automatic recognition for the first time, and conducting research on the CS asynchronous fusion, my work has made great progress in solving the challenging problems in this field compared with the previous SOTA works.
