Akinori Yonezawa (米澤 明憲, Yonezawa Akinori)(born June 17, 1947) is a Japanese computer scientist. Professor Emeritus of the University of Tokyo.[1][2] Received Ph.D. from the Massachusetts Institute of Technology (MIT).[3] Currently, a senior fellow at the Chiba Institute of Technology, Software Technology and Artificial Intelligence Research Center.[4] Former member of the Science Council of Japan.[5] Specializes in object-oriented programming languages, distributed computing and information security.[6] From its beginning, he contributed to the promotion and development of object-oriented programming, which is the basis of programming languages most commonly used today (Python, Java, C++, etc.), and served as a program committee member and chairman of the main international conferences OOPSLA and ECOOP. At the same time, he is internationally known as a pioneer of the concepts and models of “concurrent/parallel objects".[7][8] In software systems constructed based on concurrent/parallel objects, information processing and computation proceed by concurrent/parallel message passing among a large number of objects.[9] Yonezawa's concurrent (parallel) objects are influenced by Actors, the concept of which was proposed by Carl Hewitt at MIT's AI Lab in the early 1970s[10] and later rigorously formulated by Gul Agha.[11] However, concurrent objects and actors are fundamentally different. An actor is an object that does not have a "state," whereas Yonezawa's concurrent (parallel) object can have a persistent state. For this reason, concurrent (parallel) objects are often used in implementing large parallel processing software systems. Large-scale software systems built and put into practical use based on concurrent (parallel) objects include an online virtual world system Second Life,[12] social networking services such as Facebook[13] and X (Twitter),[14] and large-scale molecular dynamics simulation systems such as NAMD.[15][16]

Biography

[edit]

He graduated from Azabu High School in 1966, and graduated from the University of Tokyo, Faculty of Engineering, Department of Mathematical Engineering in 1970. He received Ph.D. in Computer Science from the Massachusetts Institute of Technology, Department of Computer Science in 1977. His dissertation is entitled "Specification and verification techniques for parallel programs based on message passing semantics".[3][17]

He engaged in research on parallel and distributed computing models at the MIT Computer Science and Artificial Intelligence Laboratory. After returning to Japan, he studied and taught at the Tokyo Institute of Technology and became a professor at the University of Tokyo, Department of Information Science in 1988.[18] He held various positions of the University of Tokyo, including director of the Information Infrastructure Center.[18] He was elected as a member of the Science Council of Japan in 2008.[5] In 2011 he retired from the University of Tokyo and became a professor emeritus. He was awarded the Medal with Purple Ribbon in 2009 [19] and the Order of the Sacred Treasure, Gold Rays with Neck Ribbon in 2020.[1][2][20][21] After retiring from the University of Tokyo, he served as deputy director of the RIKEN Computational Science Institute until 2015, contributing to the operation of the supercomputer "K".[22] Then, he served as Director of the Software Technology and Artificial Intelligence Research Center, the Chiba Institute of Technology until 2022.[23] Currently, he is a senior fellow at the research center.[4]

In 2012, an international symposium commemorating Yonezawa's 65th birthday was held in Kobe, and a collection of papers (Festschrift) authored by the symposium participants was published by German publisher Springer-Verlag in 2014.[24]

Additionally, an article overviewing Yonezawa's computer software research up to around 2003 was published in a journal of the Japan Society for Software Science and Technology.[6]
