Career summary of Professor Shigeaki Ogibayashi

He graduated department of physics Tohoku University, Sendai, Japan, in 1969, and finished master degree majoring in physics in 1971.

In 1971, he started his career working in the R & D department of Nippon Steel Corporation as a research engineer in the field of metallurgy in steelmaking and solidification. He typically devoted to the development of quality-related technologies in continuous casting of steel slabs and blooms and contributed to increasing the continuous-casting ratio in most of the steelworks in Japan from 5% in 1971 to 100%.

He received his doctorate in engineering from Tokyo University in 1992 for his piles of work on the formation mechanism of centerline segregation of continuous casting and the invention and development of soft reduction technology to overcome the problem.

In 1997, He retired Nippon Steel and started his new career at Chiba Institute of Technology as a professor in the department of management information science. In the first several years since starting activities in Chiba Institute of Technology, he was mainly engaged in administration field, organizing a new faculty of social systems science, a new course of graduate school, etc. Since then, he started to focus on research activities in the field of modeling and simulation, especially in the agent-based modeling (ABM) of social systems. He has so far developed Agent-Based models of macroeconomic, bullying and pandemic phenomena. After the retirement from Chiba Institute of Technology in 2017, he continues to work on Agent-Based Modeling of socio-economic phenomenon with special interests for proposing a new methodology using entirely bottom-up ABM to elucidated the causal mechanism of social phenomenon.
