Professor Nishizeki has established himself, both nationally and internationally, as a world leader in the computer science, in particular, algorithms for planar graphs, edge-coloring, network flows, VLSI routing, graph drawing and cryptology. His publication list includes three co-authored books, five edited books and more than two hundred technical papers in leading journals and prestigious conferences such as JACM, SIAM Journal on Computing, Algorithmica, Journal of Algorithms, Journal of Cryptology, STOC, ICALP, and SODA. The quality of his work is best illustrated by the fact that a number of his papers have been selected as best papers and have also been invited to special journal issues. One of his co-authored books, ``Planar Graph Drawing'' published in 2004, was written with Dr. Md. Saidur Rahman who received Master of Information Sciences and Ph. D. degrees under Professor Nishizeki's supervision and is now a professor of BUET. The book is considered as the most valuable pioneering work of planar graph drawings, and it has been widely distributed over the world.
As the most active and renowned computer scientist in Asia, Professor Nishizeki has also made a great contribution to build a community of computer science researchers in the Asia and Pacific region. In 1990 he founded the first International Symposium on Algorithms and Computation (ISAAC) for the purpose of expanding the research community among the Asian and Pacific countries, which has been held in Asia-Pacific region annually since then. Thanks to this conference, the computer science in Asia has successfully flourished. ISAAC is no doubt a landmark in the Asian society of computer science. Besides this attempt, Dr. Nishizeki has also made continuous efforts at supervising research students from all over the world. Most of them have remained academics in research universities and they are active as leading researchers in their own countries.
Professor Nishizeki is a Fellow of many distinguished academic and scientific societies including ACM, IEEE, IEICE of Japan, Information Processing Society of Japan and Bangladesh Academy of Sciences. He has been serving as Advisory Committee Chair of ISAAC since 1990, and active as Steering Committee member of Graph Drawing conference since 1993. Dr. Nishizeki has also kept him busy as editors of prestigious journals. He is currently serving Algorithmica, Journal of Combinatorial Optimization, and Computer Science Review as an editor, and Springer Book Series Geometry and Computing and Journal of Graph Algorithms and Applications as an advisory editorial board member. He also served as editors of Discrete Mathematics and Theoretical Computer Science (1997--2006), Journal of Information Processing (1988--1994), Transaction of IEICEJ (1989--1991), Journal of IEICEJ (1983--1986).
Professor Nishizeki has been actively associated with world leading researchers, constantly invited by major universities over the world. Among them are Carnegie Mellon University and UC Berkeley in the United Sates, Waterloo University and Simon-Fraser University in Canada, Bonn University and TU Berlin in Germany, University of Sydney in Australia, Taiwan National University and Academia Sinica in Taiwan. He was also a Visiting Research Mathematician at Carnegie-Mellon University from 1977 to 1978, and has been serving as an advisory professor of East China Normal University in Shanghai from 2006.
For his great achievements in computer science, Professor Nishizeki is awarded ICF Best Research Award by International Communications Foundation in 2006. In 2003 Funai Information Science Promotion Award was presented to him by Funai Foundation for Information Technology, and in 1998 TELECOM Technology Award by The Telecommunications Advancement Foundation.
