Computer and Mathematical Sciences

Explore the nature and potential of information sciences

Department of Computer and Mathematical Sciences is engaged in research in the area of information sciences for the future. Our research subjects include basis of information sciences such as computer sciences and software sciences, next-generation computational sciences for super-parallel computing and large-scale high-speed computing, and a wide range of applications of information sciences associated with mathematical sciences. Also we are devoted to developing future leaders of those fields. Our department consists of the foundation part and the cooperation part. The foundation part is made up with four sections: Mathematical Structures, Applied Mathematical Science, Computation Science and Systems, and Software Science and Systems. Those disciplines have existed from the very beginning of the GSIS. The cooperation part is divided into five sections: Logic for Information Science, Communication Theory, Ultra-highspeed Information Processing Algorithm, Information Security, and Environmental Informatics.

Human-Social Information Sciences

Explore the relation of information, society and humanity

What changes would the information society bring? To begin with, what framework; spiritual, cognitive, or cultural, would information need be comprehended and propagated? What are the solutions to the social problems the information society inevitably poses? We, in Department of Human-Social Information Sciences, are striving to answer those questions in the form of interdisciplinary research and education. The members constituting our group are trained in wide range of subjects, including, cognitive psychology, philosophy, linguistics, sociology, media theory, regional sciences and civil engineering. Recently we have been engaged in reconstructive activities of the earthquake damage of 2011. In particular, our activities include recording and analysis of resident participation in the disaster affected area, opinion polls of the citizens of Sendai city, flows of the emergency goods, the traffic pattern of the post-disaster days. Those researches have been publicized in the Japanese mass media.
