Biography

Sugiyama was born on September 17, 1945 in Gifu Prefecture, Japan. He did both his undergraduate and graduate studies at Nagoya University, earning a doctorate in 1974. He then worked for Fujitsu until 1997, when he became a professor at the Japan Advanced Institute of Science and Technology. At JAIST, he became a center director in 1998, dean in 2000, and vice president in 2008. He died on June 10, 2011.[1][2]

In the 1990s, Sugiyama also served as one of the directors of the Information Processing Society of Japan.[2]

Research

Sugiyama is best known for his work with Tagawa and Toda introducing layered graph drawing, now also known as Sugiyama-style graph drawing.[2][3] Sugiyama also wrote highly cited papers on other topics in graph drawing including maintenance of the "mental map" when a drawing is modified,[4] drawings that simultaneously display both the adjacencies between vertices in a graph and a hierarchical structure on the same vertices,[5] and the control of edge orientations in force-based algorithms.[6]

Books

Sugiyama was the author of several books on graph drawing and knowledge engineering.[7] His book Graph drawing and applications for software and knowledge engineers (World Scientific, Series on Software Engineering and Knowledge Engineering, Vol. 11, 2002, ISBN 978-981-02-4879-6) is a translation into English of a 1992 Japanese book that was the first book in any language on the subject of graph drawing.[2] His book Knowledge Science (with Atsushi Shimojima and Akiya Nagata) was also translated into Korean (BADA Publishing, 2005).

gollark: What?
gollark: Even more kind of infuriating is that due to the inherent randomness some people got, what, three?
gollark: I mean, with cave hunting there's *some* skill or at least really fast F5ing/internet.
gollark: It's kind of horribly infuriating that you can only get the most valuable dragons of all through RNG.
