Julien Demouth

POSTECH Computer Graphics Lab.

I am now working as a R&D engineer in Ubisoft, Paris.

Short description

I was a postdoc at POSTECH in Computer Graphics Lab where I worked with Prof. Seungyong Lee and his students (from Oct. 2008 to Oct. 2009). Prior to that, I was a PhD student at LORIA in the project VEGAS. I received my PhD degree from Université Nancy 2 on November 2008 (see below for a link to my PhD dissertation, in French).
