Since this is a completely different research field from my undergraduate days, I have a lot of work to do, and I will do my best!

I will try my best to speak English fluently!

Favorite food:ramen(Jiro ramen), sushi(seafood bowl), udon, green onion

Hobbies:Basketball (since the first grade of elementary school), muscle training (4 years in the gym, bench press 140kg (goal 150kg!)), driving, karaoke, music (YOASOBI, Green Yellow Society, My Hair is Bad, back number)

I am second to none in my ability to continue and multitask!
