Dr. Toyo (Toyotaro) Suzumura is a research scientist and global head of scalable graph computing research in the IBM Research Division, at the Thomas J. Watson Research Center in Yorktown Heights, New York.  He is also a principal investigator of a project called "scalable graph learning to mitigate financial crimes" in the MIT-IBM-Watson AI lab.  in IBM Research, he is also a global co-lead of AI (Artificial Intelligence) for finance - by leading a global research team of a scalable graph computing platform and also AI for financial crimes such as anti-money laundering. 

He also served as a visiting full professor at Barcelona Supercomputing Center in Spain as well as a visiting researcher at the University of Tokyo in Japan. In 2017 he served a program committee chair for one of the largest big data conferences named IEEE BigData 2017 - organizing more than 1000 researchers from worldwide.  He has been also leading a team that continues to win the world championship in supercomputing competition called Graph500 10 times in total since 2014.  He is also a recipient of two IBM Outstanding Technical Achievement Awards (2018) for his scientific contributions to graph computing. 

He holds his Ph.D. in computer science from Tokyo Institute of Technology. His Ph.D. thesis focused on Grid computing and large-scale distributed computing systems. His current research topics include artificial intelligence, machine learning, large-scale graph analytics, deep learning, big data processing middlewares, supercomputing/high-performance computing, and microscopic simulation platforms on top of parallel and distributed computing environments.  He has been leading commercial projects with financial institutes to provide production-ready AI systems to detect financial frauds over millions of financial transactions. 

After obtaining a Ph.D. in 2004,  he joined IBM Research – Tokyo (namely TRL: IBM Tokyo Research Laboratory ) in 2004 as a research scientist and has also continued to serve professorship in academia since 2009. Since April 2009, he had served as a visiting associate professor at Tokyo Institute of Technology in Japan and led his own research laboratory named Suzumura laboratory - supervising 16 master and Ph.D. students.   Since October 2013, he moved to Smarter Technology Cities Center in IBM Research – Ireland as an international assignment -  leading a large-scale traffic simulation project in Dublin, Ireland.  During the stay, he also served as a visiting associate professor at University College Dublin as well as an adjunct professor at Tokyo Institute of Technology in Japan.  After the project was successfully finished,  he completely transferred to IBM US,  IBM T.J. Watson Research Center in New York - a headquarter of IBM Research as a new journey. 

He served a co-principal investigator for two Japanese government projects funded by Japan Science Foundation that aim at building next-generation big data processing middlewares and libraries. One of his notable achievements is that he has kept leading the team of winning the first place at the world competition of “Big Data” processing on supercomputers called “Graph500” ( 10 times in total since June 2014 by proposing a novel and highly scalable graph search algorithm on massively parallel and distributed computers and successfully implementing it on the Japanese K
supercomputer. He has also led a project “ScaleGraph” ( of developing an open-source library for billion-scale graph analytics.

He has published more than 90 reviewed paper for top-quality international conferences and workshops, and 25 international patents, and also served invited speakers, workshop chairs and/or program committee members for top-tier conferences such as ACM/IEEE Supercomputing and ACM International World Wide Web Conference. He served as a PC co-chair for IEEE BigData 2017, ICCC 2018, Industrial PC co-chair for IEEE BigData 2016, an area chair for IEEE Cloud.
