Ryuzou Nishi

[Profile]

1986	I graduated in department of physics, faculty of science from Hiroshima University
1986-	I was employed as a wireless system engineer at Mitsubishi Electric Corporation Co.,Ltd., where I developed and designed the high efficiency modulation for wireless communication system, especially Spread Spectrum Wireless Communication System.
1991-	I was employed at Kyushu Matsushita Electric Co.,Ltd., where I developed and designed spread spectrum wireless communication systems and broadband wireless communication systems.
2002-	renamed to Panasonic Communications Co.,Ltd.(PCC)
2004-	I was employed as a resident researcher at Institute of Systems, Information Technologies and Nanotechnologies (ISIT)(renamed from Institute of Systems, Information Technologies on 2008), where I had researched the security, especially key management technique for home network.
2006-	Now, I am employed in developing security and wireless techniques in PCC.
2010-	renamed to Panasonic System Netoworks Co.,Ltd.(PSN)
