About me

I am a Research Scientist & Artist at Spellbrush, a start-up company passionate about making lifelike AI-powered Anime Waifus and Husbandos for us Otakus. I work closely with my producer homies Dr. Junan Zhang and Prof. Lauri Juvela on research that would help other music producers. I am also a co-founder of Amphion Amphion GitHub stars, an open-source toolkit for Audio, Music, and Speech Generation.

My research interests include:

  • AI Music
  • Vocaloid
  • Voiceroid
You will know what I am talking about if you are also an Anime Otaku ;)
