CV: pdf (Last updated: 2025-07-09)
I'm a researcher in Computational Speech and Language, with a Ph.D. in Interdisciplinary Sciences from SOKENDAI, Japan (2020). Currently, I serve as a Research Fellow at Nanyang Technological University, Singapore. My research centers on developing novel Speech and Language Processing Systems, including Automatic Speech Recognition, Generative AI, and Machine Learning. Right now, I'm particularly interested in Fake Speech Detection, as well as exploring AI applications in human-computer interaction and natural language processing.
I do programming and drawing as hobbies. More below.
