Welcome to Satoshi Ikehata's Home Page

About me

- From June 2014 to November 2016, I was a post-doc researcher in Washington University in St. Louis and worked with Dr. Yasutaka Furukawa.

- I got my Ph. D in 2014 and MS in 2011 in University of tokyo under the supervision of Prof. Kiyoharu Aizawa.

- I got my BA of Psychology from the University of Tokyo in 2009 under the supervision of Prof. Takao Sato.

- I worked for Visual Computing Group at Microsoft Research Asia as a visiting student in 2011, supervised by Dr. Yasuyuki Matsushita.
