Shinji ITAYA

I hold a PhD in Engineering from Kyushu University, Japan, specializing in Conservation Biology and Environmental Engineering. With over 20 years of experience in environmental consulting and more than 20 years of teaching, I possess intense research, data analysis, and fieldwork expertise. I am fluent in English and Japanese and excel at bridging scientific knowledge with practical conservation strategies.
