Masami Tatsuno received his PhD in Applied Physics from Waseda University, Japan. From 1999 to 2002, he was a postdoctoral researcher at RIKEN Brain Science Institute, Japan, where he conducted information geometric analysis of spike trains under the mentorship of Shun-ichi Amari. In order to acquire experimental skills to further his interest in neural computational principles, he joined the group of Bruce McNaughton at the University of Arizona in 2002. There, he conducted multi-electrode recording from various brain areas, and studied memory-trace reactivation during slow-wave and REM sleep and the fluctuation of cortical Up and Down states. In 2005, he was appointed as a research faculty of the University of Arizona. In 2009, he accepted the faculty position at the University of Lethbridge .
