The First International Aizu Conference on Biomedical Informatics and Technology (ACBIT 2013) is an international event, which will make a celebrating occasion of the 20th Anniversary of the University of Aizu. The University of Aizu has the largest School of Computer Engineering and Science in Japan. Major measures for the revitalization in Fukushima Prefecture include on-going provision of wide-ranging support for mental health care; encouragement of medical industry clusters including biomedical research, drug development focusing on cancer treatment, creation of industries to meet the needs of an aging society; creation of centers for early diagnosis and state-of-the-art treatment of diseases and disorders. With an emphasis on the applications of computer, physical, engineering and mathematical models for solving modern challenging problems in medicine, biology and health; the conference aims to bring biologists, medical and health-science researchers together with computer-science and computational scientists to focus on problems at the frontier of biomedical informatics and technology. A goal of this meeting is that the interactions of scientists across several disciplines will lead to the identification of new scientific investigations, shape future directions for strategic research, and help industrial users apply advanced computer techniques for solving practical life-science problems. As another important aspect, the conference aims to provide opportunities for postgraduate research students to present latest research results and establish links with experts across several scientific disciplines.
