Information science in the Department of Information Sciences is comprised of the 3 fields of "basic mathematical information," which handles "information" related to various nature, social and human phenomena in a mathematical manner with mathematics as the basis, "applied mathematical information," which handles basic mathematical information in a practical manner, and "computer science," which handles systems that process information; the aim of this department is to foster the ability to quantify information and carry out scientific analysis.

Research Groups & Research Areas

  • Basic Mathematical Information

    Mathematical information is an area of study focused on information technology and its accompanying mathematics. It is concerned not only with addressing social challenges through the application of mathematical ideas accrued over millennia of human history, it is also used in conjunction with the field of information science to come up with entirely new mathematical approaches and methods. Students in basic informatics and mathematics will study information communications and information security technology theory as it pertains to quantum information, graph theory, cryptographic theory and other topics.

  • Information and Data Science

    Information and data science is an area which holds great promise for society in its ability to use the diverse abundance of information (data) saturating our world to create new knowledge and value. Researchers develop new data analysis methods backed by correct mathematics which are applied in a broad range of areas, including public data, genomics data, health care data, and sports data, to elucidate new, scientifically grounded findings.

  • Computer Science

    The field of computer science is focused on creating mathematical models and developing technologies that will enable computers to be used in addressing a variety of modern challenges. Students will learn about VR/MR/AR, musical, audio and video media processing technology, computer networks, artificial intelligence, programming language theory and much more.
