Biostatistics deals with the application of statistical techniques to scientific research in health-related fields, including medicine, dentistry, genetics, nursing and public health, and the development of new tools to study these areas. Since the beginning of the twentieth century, the field of biostatistics has become an indispensable tool in health science research.

By developing new quantitative methods, characterising underlying theory, and marking innovative applications to substantive and demanding scientific problems, biostatisticians play a leading role in the advancement of biomedical, pharmaceutical and public health research. Demand for expertise in biostatistics continues to be high in academia and in the public and private sectors, particularly in settings emphasising research in pharmaceutical and biotechnology.
