Short Bio: I was born in Recife Brazil to
Japanese parents. My father
wrote papers on fish biology (piscicultura) at
the Universidade Federal de
Pernambuco. He was
dispatched to Brazil by Japan
International Cooperation Agency. We left Recife for Tokyo when I
was two and a half. I obtained BA and MA
at International Christian
University, studying representation theory and combinatorics with
Professor Hiroshi
Suzuki. I went back to Recife Brazil in 2016 with generaous help
of Recifenses.
