Hi there! I’m a Postdoctoral Research Associate at Yale University’s Department of Biomedical Informatics and Data Science. Previously, I received my Ph.D. degree in Computer Engineering from Steves Institute of Technology. I got the M.S. degree in Multimedia Telecommunication from University of Liverpool. Before that, I obtained my B.Eng degree in Telecommunication Engineering from the Xi’an Jiaotong-Liverpool University.

My research span Natural Language Processing (NLP), Multimodal, Audio/Speech Processing, Trustworthy AI, with applications in finance and healthcare.
