What is Biostatistics?

Biostatistics is the study of the application of statistical inference and methods to health-related fields such as public health, medicine, and biology. As one of the core disciplines of public health, it is concerned with the quantitative aspects of the design, conduct, analysis, and interpretation of health science research.

Biostatistical methods are used in a wide range of public health activities, including assessing causal hypotheses of disease and injury, evaluating the effectiveness of intervention programs/policies/trials, and monitoring and detecting population health trends.

What we do in Biostatistics

Our faculty are engaged in the development and application of biostatistical methods and their teaching for a wide range of research in public health. The development of the methodologies we pursue is always done through collaboration with researchers in other health-related fields, such as public health and medicine.

Our research is usually funded by government agencies such as the Ministry of Education, Culture, Sports, Science and Technology and the Ministry of Health, Labor and Welfare. In addition to developing methodologies, each biostatistics faculty member is very active in interdisciplinary collaborations with regional, national, and international researchers and governments.
