I received a Ph.D. degree in Computer Science and Information Engineering from National Taiwan University, Taipei, Taiwan. I am currently a Postdoctoral Researcher at the Research Center for Information Technology Innovation, Academia Sinica, in Taipei, Taiwan. I was previously a Research Assistant at the same institute and also worked as an Applied Scientist Intern at Amazon in California, USA. I was honored the Gold Prize for the best non-intrusive systems and 1st place for the Hearing Industry Research Consortium student prizes at the Clarity Prediction Challenge, the 2nd Clarity Workshop on Machine Learning Challenges for Hearing Aids (Clarity-2022).

My research interests include deep learning, speech processing, and deep learning-based non-intrusive speech assessment model. Please kindly check the following link for more update publications.
