About Me

    I'm a Ph.D. student at CPJKU, working with Univ.-Prof. Gerhard Widmer.
    Previously a master's student from the Music Informatics Group at Georgia Tech, advised by Prof. Alexander Lerch, and a research assistant at the Academia Sinica in Taiwan, working with Dr. Yi-Hsuan Yang.
    My research focuses on computational methods for a better understanding of expressive performances, symbolic representaion, and the underlying emotions. I aim for machines to serve as a guide and tool for the comprehension of musical context within the field of music information retrieval and generation.
