graph drawing.
Education and career
Nishizeki was born in 1947 in
Fukushima, and was a student at
Tohoku University, earning a bachelor's degree in 1969, a master's in 1971, and a doctorate in 1974. He continued at Tohoku as a faculty member, and became a full professor there in 1988.[2] He was the Dean of the Graduate School of Information Sciences, Tohoku University, from April 2008 to March 2010. He retired in 2010, becoming a professor emeritus at Tohoku University, but continued teaching as a professor at

At the 18th ISAAC symposium, in 2007, a workshop was held to celebrate his 60th birthday.[8]
In 1996, he became a
life fellow of the IEEE "for contributions to graph algorithms with applications to physical design of electronic systems."[9]
In 1996 he was selected as a fellow of the
Association for Computing Machinery "for contributions to the design and analysis of efficient algorithms for planar graphs, network flows and VLSI routing".[10]
Nishizeki was also a foreign fellow of the
Bangladesh Academy of Sciences;[11] one of his students and frequent co-authors,
Md. Saidur Rahman, is from Bangladesh.
