Self-introduction
Dr. Tahara was born in 1985 in Japan. He got Ph.D. in Waseda University in 2013. He was a visiting assistant professor in UCLA (2016-2019), then moved to Waseda University as an associate professor. He moved to Hiroshima University in 2022. His research topic is circadian clock in mammals, especially chrono-nutrition.
