HOMEPAGE

Graduate students interested in the methods of biostatistics and the conduct of epidemiologic research and clinical trials are welcomed. This Department offers programs of study leading to a master’s degree and a doctoral degree. The Master of Public Health (MPH) degree program is designed to provide basic training in biostatistics as applied to a broad spectrum of health-related problems. The doctoral degree program is designed to provide advanced, research oriented training in methods of biostatistics.

Research and Education

Major research fields are biostatistics methodology and conducts of epidemiologic studies and clinical trials. In methodological work, new epidemiologic study designs which are efficient and convenient are investigated for providing new sampling and analysis methods. Causal inference is the most challenging methodological research field. Estimation of causal parameters in experimental and observational studies is developing. Several collaborative studies in epidemiology and clinical trials are ongoing. Department of Biostatistics offers “Fundamentals of Biostatistics”, “Introduction to Statistical Computing and Data Management”, “Statistical Methods in Observational Studies”, “Intermediate Biostatistics”, and “Health Data Processing Laboratory”. We give introduction to concepts of randomization, causal effects, and confounding, designs of clinical trials and observational studies. Topics include randomization, experimentation, measurement, probability, confidence intervals, and tests of hypotheses.
