I am Haruhisa Enomoto (榎本 悠久 in Japanese), an R&D researcher at Parakeet Inc. in Japan since 2025-03-01, an AI startup focusing on speech related technologies.

Previously:

  • I worked at Acompany Co., Ltd. as an R&D Engineer: 2024-04-01 – 2025-02-28.
  • I was a postdoc majoring in representation theory of algebras.

I’ve left math academia in March 2024 and joined a company in April 2024. See here (Japanese) for more details if you are interested in why I decided to leave academia.

This site will be available after March 2024, but I haven’t decided whether I will update this site or not, and its contents.

The e-mail address below will not be available after March 2024.

FD Applet - an applet for Finite-Dimentional algebras has been released!
