His directing credits include major titles such as Fullmetal Alchemist, Fullmetal Alchemist: Brotherhood, Death Note, and Bleach, including its films. He has also directed German versions of other well-known series like Food Wars! Shokugeki no Soma, Blue Exorcist, Blood Blockade Battlefront, and Darker than Black.

A notable film role is providing the German voice for Aoyama's Father in the 2018 anime film Penguin Highway. His work is almost exclusively in the German dubbing industry, contributing to the localization of Japanese animation for a German audience.
