Principal
My name is Servando Lopez Leon from Mexico. I hold a Ph.D. and a Masters degree in Electrochemistry. I have been living in Japan for 3 years and right now I have the pleasure to be the Principal here, at Saisishya.
As a scientist, I taught in the past in different countries and universities around the world (France, Canada and Mexico) where I was in charge of leading undergraduate and Ph.D. students.
With all this experience and the support of all the SSIS community I do not have any doubt the Saishya will become one of the best schools in Tokyo.
