ToyotaroSuzumura received his Ph.D. in Computer Science from Tokyo Institute of Technology in 2004 mainly focusing on Grid computing and distributed systems mainly supervised by Prof. Satoshi Matsuoka. He published top-tier international conferences such as ACM/IEEE Supercomputing and IPDPS during his Ph.D, and also spent part of his Ph.D. research activities in San Diego Supercomputing Center, eXtreme Scale Computing led by Prof. Dennis Gannon, and Innovation Computing Laboratory led by Prof. Jack Dongarra. He joined IBM Research - Tokyo in 2004 and had involved with several projects such as high performance XML processing, the PHP scripting language, stream computing, the X10 programming language and so forth. Since 2010, he has started to develop an X10-based billion-scale agent simulation platform on highly distributed systems and its application to large-scale traffic simulation. He has also explored billion-scale large scale analytics and been leading an open source graph library called ScaleGraph (http://www.scalegraph.org) and also continuously achieves 3rd or 4th place in the big graph processing competition called Graph500. He also had taken a role of a visiting associate professor at the Graduate School of Information Science and Engineering of Tokyo Institute of Technology since April 2009 for almost 5 years and supervised 16 students including 3 Ph.D. students. Since April, 2013, He also serves as a visiting associate professor at University College Dublin, Ireland. He has published 50 reviewed paper for international conferences and workshops, 41 domestic conferences, and 12 international patents. He is now a co-principal investigator for two Japanese government projects called "JST CREST" by leading both large-scale graph analytics and billion-scale agent simulation towards exa-scale computing environment.
