I am an Integrated M.S. & Ph.D. student at Korea University, advised by
Seong-Whan Lee, and a member of the PRML Speech Team.

My research focuses on speech generation and affective speech modeling, including expressive and controllable speech synthesis, neural vocoders, voice conversion, and generative models.
