About me.
Currently, I am working in Shanda AI team as an AI scientist, focusing on solving the application and research of large language models in Mental Health. This is a continuation of my doctoral project, hoping to contribute my own strength to digital health.
I got my Ph.D. degree in the School of Electrical and Electronic Engineering at Nanyang Technology University (NTU), Singapore. I completed my Bachelor's degree at the School of Electronics and Information Engineering, Harbin Institute of Technology, China.
My PhD research focused on developing AI systems to understand human behaviors, including voice, language, facial expressions, and body movement from audio-video recordings. For six years, I worked on a psychiatric project to automatically diagnose and assess mental illness patients in collaboration with NTU and IMH Singapore.
Previously, I was a AI Research Scientist at Mindsigns Health, a startup company using machine learning for long-term monitoring of people with mental disorders. I then joined HUAWEI 2012 laboratory as a Senior AI Engineer, working on multi-modal search and recommendation, large language models, and multimodal model research.
